It is aimed to suppress water intrusion into an internal accommodation space for accommodating a ferrite and the adhesion of water to a male terminal by providing a sealing member. A connector (10) includes an inner housing (16), an outer housing 14 including a rear receptacle (30) into which the inner housing (16) is fit, and ferrites (12) including ferrite-side insertion holes (48) through which busbars (18) are inserted. The ferrites (12) are accommodated into internal accommodation spaces (S) formed inside by the inner housing (16) and the rear receptacle (30) in a fit state. A sealing member (20) is sandwiched between the rear receptacle (30) and the inner housing (16) to suppress water intrusion into the internal accommodation spaces (S).
