An electrical contact point including: a first contact and a second contact capable of forming an electrical contact each other, wherein: the first contact includes an alloy containing layer having alloy parts made of an alloy containing tin and palladium and a tin part made of tin or an alloy having a higher ratio of tin to palladium than the alloy parts with both the alloy parts and the tin part exposed on an outermost surface; and the second contact includes a dissimilar metal layer made of metal having a higher hardness than the alloy containing layer and containing neither tin nor palladium on an outermost surface.

Electrical contact point, connector terminal pair and connector pair

It is aimed to provide a press-fit terminal connection structure in which a board connecting portion of a press-fit terminal is press-fit into a through hole provided in a printed circuit board and which can combine the suppression of scraping of a surface layer and a reduction of a necessary load when the press-fit terminal is inserted into and withdrawn from the through hole and an improvement of a holding force for keeping the press-fit terminal inserted in the through hole. In the press-fit terminal connection structure, the press-fit terminal includes, at least on a surface of the contact point portion, an alloy containing layer mainly containing tin and palladium, and the through hole includes a tin layer on an outermost surface of an inner peripheral surface including at least the contact point portion.
