An electrical connector includes connecting members arranged in an arrangement direction; and a housing member for accommodating the connecting members. The connecting member includes a terminal connected to the mating connector, and a holding member for holding the terminal. The terminals includes a connecting portion at one end in a longitudinal direction for connecting to a circuit portion of the circuit board, a contact portion at the other end in the longitudinal direction for contacting with a mating contact of the mating connector, and a held portion near the connecting portion in the longitudinal direction and held with the holding member. The housing member is be movable linearly or rotatable relative to the holding member. The housing member includes a guiding surface for guiding the mating terminal. The terminal includes a deformable portion opposite to the connecting portion. The deformable portion deforms when the guiding surface guides the mating terminal.
