A horizontal electric connector includes an insulating housing, a first electric contact, with a contacting part that is press-fitted into the housing from the rear and contacts a counterpart conductive part, and a leg that extends from the contacting part, comes out of the housing at the rear and descends, and a second electric contact, with a contacting part that is press-fitted into the housing from the rear at a position lower than the first electric contact and contacts a counterpart conductive part, and a leg that extends from the contacting part, comes out of the housing at the rear and extends forward along the bottom of the housing. A leg supporting part is provided on the bottom of the housing, into which the leg of the second electric contact is press-fitted from the rear, to prevent deformation of the leg.
