In the IC module used in the 92141 publication, the IC chip, the conductive path, and the external terminal are on the same side of the board, so the IC chip and the conductive path are mechanically connected while exposing the external terminal. and required a cover plate for insulating protection. Therefore, similar to the above case, there were problems in that the manufacturing process became complicated and the thickness increased.

ある。 The present invention eliminates the above-mentioned drawbacks of the conventional ones, has a cover plate that does not adversely affect the IC chip even when subjected to pressing force from the contact of an external terminal, and is used to protect the board from deformation and insulation. The purpose is to provide IC cards that are not needed.

The present invention is formed in such a state that an IC module formed as shown in (A) below is fitted into a recess of a card body with the surface of the board on the external terminal side facing the front side and the IC chip side facing the recess. An IC card characterized by:

This IC module is formed by extending a path to the back side of the external terminal and connecting it to the external terminal via a through hole.

An embodiment of the present invention will be described with reference to the drawings. In FIG. 3, the substrate 4 and the molding material 2 are extended, and the contact points 5 are provided away from the mounting portion of the IC chip 3. If the distance from the nearest contact point 5 to the IC chip 3 is l, and the thickness of the substrate 4 is t, for example, in the case of a glass epoxy resin substrate, it is preferable that l≧10t, and more preferably that l≧20t.
各リード線８と各スルーホール５の裏面とは、
それぞれ導電路１０により独立接続されている。 The back side of each lead wire 8 and each through hole 5 is
Each of them is independently connected by a conductive path 10.

となくICの正常な動作を確保することができる。 Because of this structure, even if a pressing force is applied to the contact point 5 by the pin 6, deformation occurs only in the vicinity thereof, and the IC chip 3 and its vicinity are not affected by the deformation. Normal operation of the IC can be ensured without causing peeling of the bonding or deformation or breakage of various parts as described in 3.
さらに、スルーホール７の位置もICチツプ３

い。 Furthermore, the position of through hole 7 is also the same as that of IC chip 3.
Since it is far away from the IC, even if the drug enters through the through hole 7, it will not affect the IC.
本発明により、外部端末の接触子から押圧力を

効果を奏する。
According to the present invention, even if a pressing force is applied from a contactor of an external terminal, the IC chip is not affected, the board is not deformed, and the bonding (die bonding) between the IC chip and the board does not peel off.
The IC chip and board do not cause damage to lead wires, etc., ensuring normal operation of the IC.
There is no need for a cover plate to protect the board from deformation or insulation, simplifying the manufacturing process, and
The thickness can be reduced, which has an extremely large practical effect.
