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of scraping of a surface layer and a reduction of a necessary load when the press-fit terminal is inserted into and withdrawn from the through hole and an improvement of a holding force for keeping the press-fit terminal inserted in the through hole.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.
