In an electrical connector, a housing includes opposite front and rear end walls, and an insertion slot that is formed between opposite upper and lower inner wall surfaces extending in a front-rear direction and that opens at the front end wall. A terminal has a movable arm and a stationary arm that are disposed respectively on two sides of the insertion slot. The movable arm has a front barb-like contact portion proximate to the front end wall. The stationary arm is tapered forwardly, and has a front end distal from the front end wall, and an inclined contact face that is inclined rearwardly and gradually toward the insertion slot from its front end. The electrical connector has a miniaturized construction and reduces an insertion force for inserting a printed circuit board.
