A waterproof connector is low in manufacturing cost and has an enhanced waterproofness by complete prevention of the entry of water from a core wire being enabled. A cover portion is formed on an end portion of a housing and on the cover portion there is mounted a rubber-like elastic member having a semi-circular accommodation groove permitting a covered electric wire to pass therethrough. An upper cover portion is welded to the cover portion by ultrasonic oscillation. On the upper cover portion there is mounted a rubber-like elastic member brought into pressure contact with the covered electric wire together with the rubber-like elastic member as well as a core wire waterproofing member. When the ultrasonic oscillation is made, the core wire waterproofing member and a bottom surface portion of the cover portion are welded to each other. In this welded portion, a core wire of the covered electric wire whose covering portion has been removed when the ultrasonic oscillation is made is fixed in a state of its being embedded therein. |
