To enable connecting one side connector with the other connector easily without changing the position of the other connector in connecting two connectors mutually.

The board connector 185 comprises the female line terminals 185a to 185e which extend in a line shape to the laminating direction of the electric apparatus 120 to 160. The male line terminals 120b to 160b of the electric apparatus connector 120a to 160a are inserted in and connected with the female line terminals 185a to 185e from a direction perpendicular to the long length direction of the female line terminals 185a to 185e. This makes the male line terminals 120b to 160b connect with the female line terminals 185a to 185e at an optionally selected position of the long length direction of the female line terminals 185a to 185e, and thereby the position of the electric apparatus connectors 120a to 160a can be easily changed without changing the position of the board connector 185.
