[Problems to be solved by the invention]
When the electronic component is mounted on the surface of the board opposite to the mounting surface of the connector as in this conventional example, the thickness becomes considerable and the volume of the housing of the electronic device increases. This does not follow the actual situation of downsizing / thinning electronic devices.

In addition, when electronic components and connectors are mounted on the front side and the back side of the board surface of the board as in this conventional example, other parts cannot be placed on each mounting surface on the board, and wiring is reduced. There is a problem that a so-called dead space is formed and wiring efficiency is deteriorated. Further, when the electronic component and the connector are mounted at positions facing each other through the substrate, the dead space can be reduced, but the dead space is still present.
