Wire harness

A wire harness comprising:

• a first wire bundle that includes a plurality of wires;
• a second wire bundle that includes fewer wires than the first wire bundle, each of the wires of the first wire bundle and each of the wires of the second wire bundle including:
• a conductor,
• an insulating covering that covers an outer circumference of the conductor, and
• an exposed portion that is exposed from the insulating covering;
• a splice body at which the exposed portions of the first wire bundle and the exposed portions of the second wire bundle are bonded;
• and
• a waterproofing cover formed of a resin material that integrally covers:
• the splice body,
• outer surfaces of the insulating coverings of the first wire bundle, and
• outer surfaces of the insulating coverings of the second wire bundle,
• wherein:
• a first covering length is defined as a length of a region that the waterproofing cover covers the outer surfaces of the insulating coverings of the first wire bundle,
• a second covering length is defined as a length of a region that the waterproofing cover covers the outer surface of the insulating coverings of the second wire bundle,
• the first covering length is longer than the second covering length, and
• the first wire bundle includes a first number of wires, the second wire bundle includes a second number of wires, and a first difference between the first number of wires and the second number of wires determines a second difference between the first and second covering lengths.
