To reduce the parts count as small as possible, and to provide sufficient sealability against a liquid.

A core wire 11, an insulation inner coating skin 12 and a shielding layer 13 are exposed in this order in an end of a shielded cable 10, and a connection terminal 2 is connected to a tip of the core wire 11. An exposed portion of the shielding layer 13 is made to contact with an inner peripheral surface of a cylindrical body part 30 inside the body part 30 formed by a conductive material, and the end of the shielded cable 10 is extended outwards from one end side opening thereof, so as to insert the shielded cable 10. A portion ranging over from one end of the body part 30 up to a connection portion between the core wire 11 and the connection terminal 20 through an exposed portion of the insulation inner coating skin 12 is insert-molded inside a molded part 40.
