Patent number: 9735488Abstract: A board connecting connector includes a board retaining portion and a terminal retaining portion. The board retaining portion accommodates a board, and the terminal retaining portion accommodates terminals. When the board retaining portion and the terminal retaining portions are in a state of being fit to each other, terminal portions provided on a sheet surface of the board and elastic contact portions of the terminals contact to each other. Each of the terminals includes an elastic deformation portion having a contact portion and an inspection portion, with which an inspection jig contacts to inspect the terminal. The elastic deformation portion is formed by notching on a surface of a cylindrical part that is formed by bending sheet metal.
