Wire harness and manufacturing method of wire harness

A wire harness comprising:

• a plurality of harness components each of which includes an electric wire group including a plurality of electric wires and a sheet-shaped insulating exterior member housing a protection target region of the electric wire group inside, wherein
• at least one first harness component and at least one second harness component are provided as the harness components, the first harness component including a first electric wire group as the electric wire group and a pair of first exterior members that sandwich and house a protection target region of the first electric wire group inside and serve as the exterior member, the second harness component including a second electric wire group as the electric wire group and a second exterior member that is folded, houses a protection target region of the second electric wire group inside a fold, and serves as the exterior member,
• the first harness component includes joint portions in contact with each other between the pair of the first exterior members, and a weld having two free ends where the joint portions are welded to each other along an axial direction of the protection target region of the first electric wire group between the joint portions in contact with each other,
• the second harness component includes joint portions in contact with each other at tips of the fold of the second exterior member, and a weld having two free ends where the joint portions are welded to each other along an axial direction of the protection target region of the second electric wire group between the joint portions in contact with each other, and
• the plurality of harness components are integrated by welding the joint portions between the exterior members of the plurality of harness components.

A manufacturing method of a wire harness, comprising:

• a first installation process of placing one sheet-shaped insulating exterior member on an installation surface of a first mold;
• a second installation process of placing a protection target region of an electric wire group including a plurality of electric wires on the one exterior member;
• a third installation process of placing another sheet-shaped insulating exterior member on the one exterior member and the protection target region and sandwiching the protection target region between the one exterior member and the another exterior member;
• a fourth installation process of sandwiching first end portion sides and second end portion sides, viewed from the protection target region, in the one exterior member and the another exterior member between the first mold and a second mold;
• and
• a welding process of welding the first end portion sides and the second end portion sides in the one exterior member and the another exterior member along an axial direction of the protection target region.

A manufacturing method of a wire harness, comprising:

• a first installation process of bending and placing a sheet-shaped insulating exterior member into a V-shaped or U-shaped bent shape along a shape of a V-shape or U-shaped trench in the trench provided in a jig;
• a second installation process of installing a protection target region of an electric wire group including a plurality of electric wires in the exterior member having the bent shape;
• a third installation process of sandwiching end portions at tips of a fold with the protection target region as an axis in the exterior member between a first mold and a second mold;
• and
• a welding process of welding the end portions of the exterior member to each other along an axial direction of the protection target region.
