<p>PROBLEM TO BE SOLVED: To solve the problem that more contacts are needed to mount more components on a board and, if the number of contacts increases according to the present board specifications, the board itself is enlarged to deteriorate mounting efficiency. SOLUTION: A plurality of first contacts 11 are disposed on the front and back sides of end portions of a board 10, a plurality of second contacts 12 are disposed on the end faces of the end portions, a plurality of first contacts 31 are disposed on both sides of an insertion hole of a connector 20, a plurality of second contacts 32 are disposed on the bottom of the insertion hole, and the board 10 is inserted in the connector 20 to thereby connect the first contacts 11 to the first contacts 31 and connect the second contacts 12 to the second contacts 32.</p> |
