A waterproof structure for an electronic unit includes a sub-case that defines an accommodating portion that accommodates a first terminal, and has a cable guiding hole that communicates with the accommodating portion. A potting resin filled in the accommodating portion is also filled in a space between a cable and the cable guiding hole. The cable includes a first sheath that covers a conductor and is made of a first resin material, and a second sheath that covers the first sheath. The second sheath and the potting resin are made of a second resin material that is different from the first resin material.

A waterproof structure of an electronic unit includes a case that defines a housing portion housing a first terminal, and a connector that includes an insulating body attached to the case. The connector includes a second terminal that is supported by the insulating body and connects a conductor end portion of a cable to the first terminal. The insulating body includes a wall portion that partitions a part of the housing portion by covering an open portion of the case. The insulating body includes a cable lead-in portion that defines a cable lead-in hole for leading the cable into the case and is joined to the wall portion. A potting resin is filled in a space between the inner periphery of the cable lead-in hole and the outer periphery of the cable and the housing portion and cured.
