Further, since the surface of the conductor main body portion 3 of the panel penetration connecting member 1 of the conductive path has an uneven shape, the surface area of the portion in close contact with the insulating coating portion 6 becomes large, and the conductor portion 2 and the elastic seal are tentatively sealed. Even if a slight gap is generated between the elastic seal portion 5 and the portion 5, it is possible to effectively suppress the intrusion of water into the elastic seal portion 5.

Further, since the conductor portion 2 and the elastic seal portion 5 are integrally molded in the panel penetration connection member 1 of the conductive path, the conductor portion 2 and the elastic seal portion 5 are separated from each other, so that the conductor portion 2 and the elastic seal portion 5 are separated from each other. The degree of adhesion between the conductor portion 2 and the elastic seal portion 5 can be increased.

As a modification of the above-mentioned wire harness wiring method, in the panel penetration connection member setting step, the panel penetration connection member 1 of the conductive path is on the opposite side to the tip side in the insertion direction of the floor panel 150 into the through hole 150a. The electric connection portion 4 at the end of the floor panel 150 is connected to one of the electric wires 11 arranged on both the front and back sides of the floor panel 150, and the end portion on the tip side in the insertion direction into the through hole 150a is electrically connected. With the electric wire 11 not connected to the portion 4, the elastic seal portion 5 is fitted into the through hole 150a while being inserted into the through hole 150a of the floor panel 150 from the electrical connection portion 4 at the end on the tip side in the insertion direction into the through hole 150a. Further, in the through hole partial electric wire connecting step, the electric wire 11 is connected to the electric connection portion 4 on the tip side in the insertion direction into the through hole 150a to which the electric wire 11 is not connected.
