PROBLEM TO BE SOLVED: To achieve both waterproofness and noise removal characteristics.SOLUTION: A ferrite core built-in waterproof connector comprises: an electric wire WH with a terminal metal fitting 20 is attached at a tip end thereof; a connector housing 10 in which a plurality of terminal housing chambers 12A and 12B that can house the terminal metal fitting 20 are formed; a plate-like collective rubber stopper 30 assembled to the connector housing 10 so as to cover its rear end surface 10B, arranged so as to correspond to each terminal housing chamber 12A, 12B, and on whose inner peripheral surface a lip 32 tightly adhered to an outer peripheral surface of a coating of the electric wire WH is protrusively formed, and formed so as to be penetrated by a plurality of electric wire insertion holes 31 that can be inserted by the electric wire WH in a sealing state; and a ferrite core 50 having a penetrating part 52 formed substantially concentrically to at least a part of the electric wire insertion holes 31, and buried in the collective rubber stopper 30. The ferrite core 50 is arranged inside in a direction opposed to a projection direction of the lip 32 from a base of the lip 32 in the collective rubber stopper 30. |
