To obtain an apparatus and a method, in which, when two electronic components are connected electrically, they can be connected electrically by using a plurality of connection single bodies, which are formed by punching and working a copper plate and whose shape are mutually identical even when connecting terminals of the electronic components are arranged in a zigzag shape.

The distance from a positioning hole 14 up to the triangular contact part at the tip lower part of a left-side contact piece 13a is made to be a little larger than the distance from the positioning hole 14 up to the triangular contact part at the tip lower part of a right-side contact piece 13b. Then, when a connection single body 3 is turned over to the right and left directions, it becomes a state indicated in the lower figure. As a result, when a plurality of connection single bodies 3 and a plurality connection single bodies 3 indicated in the lower figure are overlapped alternately by interposing every insulating sheet between them, and their right and left contact pieces are arranged in a zigzag shape. In addition, when a plurality of connection single bodies 3 are symmetric, their contact pieces cannot be arranged zigzag.
