Abstract: An electric power converter includes a first board, a second board, and a first board-to-board connector that electrically and mechanically connects the first board and the second board. The first board-to-board connector includes a male fitting member and a female fitting member. Each of a first clamp portion and a second clamp portion of the female fitting member includes a first contact forming portion and a second contact forming portion that are curved in a protruding shape, and a first spring portion and a second spring portion that are connected to the first contact forming portion and the second contact portion, respectively, and that are curved in corrugated shapes. An insert clamped between the first contact forming portion and the second contact forming portion forms an electrical contact, and the first spring portion and the second spring portion are independently deformable.
