る。As described above, according to the first aspect of the present invention, the spring type contact pin and the spring type contact plug whose tip portions respectively elastically contact the signal circuit and the ground circuit of the other substrate directly in the vertical direction. The signal circuit and the ground circuit on the one substrate are electrically connected to the signal circuit and the ground circuit on the other substrate, respectively. Therefore, even if the mounting accuracy of the spring-type contact pin and spring-type contact plug is rough, it is possible to obtain a stable conduction state with less signal loss, and there is no possibility of conduction failure due to abrasion, which is durable. It is possible to dramatically improve the sex.
