The waterproof rubber tap is a cylindrical waterproof rubber tap structured such that, when an electric wire is inserted through the inner peripheral portion thereof and it is inserted together with the inserted electric wire into an electric wire insertion passage formed in a connector housing, it can seal, that is, can prevent water from getting into between the electric wire and electric wire insertion passage. The waterproof rubber tap includes, on the outer periphery of the opposite end portion to the insertion side thereof, a tapered sealing annular projecting portion having an outside diameter increasing toward the opposite direction to the insertion direction thereof. The tapered sealing annular projecting portion also includes an end portion having an outside diameter greater than the inside diameter of the electric wire insertion passage.
