Abstract: It is an object of the present invention to ensure a high water-stopping property of a wire harness including a waterproofing connector section that is molded from a resin, by suppressing a variation in the outer size of a seal section of the connector section. The connector section is made from a first synthetic resin that is insert-molded with a part of a terminal fitting of the terminated electric cable used as an insert section. A water-stopping section is made from a second synthetic resin that is insert-molded with a section extending from a part of the terminal fitting to an insulation coating of the terminated electric cable used as an insert section. The seal section is made from the second synthetic resin that is insert-molded with a part of the connector section used as an insert section. The second synthetic resin is softer than the first synthetic resin.
