However, the above-mentioned prior art has the following problems. In order to mount a surface mount electronic component on a board by soldering, a circuit pattern crawling on the board must be copper-clad. Therefore, for example, soldering cannot be used for a circuit pattern printed on a flexible substrate by screen printing or the like. Further, when soldering is used, a PET (polyethylene terephthalate) film or the like which is inexpensive but weak to heat cannot be used as a substrate. That is, if soldering is used, it is not possible to use a printing means and a cheap substrate which are inexpensive to manufacture.

Freon is used for cleaning soldering, but freon is an environmental problem.

In order to mount a surface mount electronic component on a board without using soldering, it is necessary to press the electrode terminals of the surface mount electronic component onto a circuit pattern on the board. However, although there is a structure in which the lead wire of an electronic component with a lead wire is pressed against the circuit pattern of the substrate, there is no conventional structure in which a surface-mounted electronic component is effectively pressed against the substrate with a simple structure. Was.

On the other hand, conventionally, there has been a structure in which a light emitting element is arranged near the push button switch in order to illuminate the key top of the push button switch brightly. However, the light emitting element is arranged at a desired position such as directly below the key top. This is not easy in structure, and there is no structure in which the light emitting element arranged near the push button switch is of a surface mount type and can be easily pressed against the substrate.

A surface mount type light emitting device having a surface directly provided with an electrode terminal, and a flexible substrate provided with an electrode pattern on the surface in contact with the electrode terminal, wherein the surface mount type light emitting device is provided on the flexible substrate. The flexible substrate is placed on the surface, and an elastic resilient plate is applied to the back surface of the portion on which the surface-mounted light-emitting element is mounted. An electrode in which the electrode terminal provided in the surface-mounted light-emitting element is provided on a flexible substrate by sandwiching the resilient plate and the surface-mounted light-emitting element with a holding member formed of an elastic plate disposed on the side. A press-fitting pattern is provided, and furthermore, an actuating object that can move up and down is arranged in the case, and a switch contact is arranged below the actuating object, and the upper end of the actuating object is pulled out above the substrate. When A surface-mount type light emitting device with a push button switch that.
