An electrical connector includes a housing and a plurality of terminals. Each of the terminals is formed of a sheet metal and held by the housing. Each of the terminals has a contact section to contact with a mating terminal and a connecting section to be connected to a circuit board each forming a continuous flat sheet surface. The contact section has a contact surface that slidably contacts with the mating terminal so as to extend in a connector fitting direction, and the plurality of terminals is arranged so that adjacent terminals have the contact surfaces parallel to each other.
