Each of the connection pins thus formed is connected to the wiring pattern formed on the sub-board. When the main body is mounted on the main board, each connection pin protruding from the bottom surface of the main body is connected to a corresponding wiring pattern formed on the main board.

Thus, it is not necessary to connect the connecting portion of the sub-board and the connecting portion of the main board with an electric wire as in the prior art. For example, it can be connected to a predetermined wiring pattern by solder dipping or the like. Therefore, wiring work between the sub-board and the main board becomes unnecessary, and assembling can be performed easily, assembling cost can be reduced and productivity can be improved.

When each of the connection pins protrudes from the vicinity of the lower end on the side surface of the main body, by minimizing the length of the connection pin, the component cost of the connection pin can be reduced, and the main body can be reduced. Since the space occupied by the connection pins in the inside is minimized, the electrical connector itself can be configured to be small.
