An end sealing structure of an electric heating pipe and an electric heating pipe system are provided to prevent water leakage and to prevent the heat of the electric heating wire from being applied to the worm water pipe. An end sealing structure of an electric heating pipe(100) comprises electric heating wires(110). A thermal medium is filled in the electric heating wire. The electric heating wire is heated when the electric power source is supplied through a electric wire(120). In the inner end of the warm water pipe, a connection portion(110a) where the end of the electric heating wire and end of the electric wire are electrically connected is formed. In the end of the warm water pipe, a cylindrical first sealing member(140) is inserted. The electric wire penetrates the cylindrical first sealing member. The first sealing member is circular silicon rubber in which a first through-hole is formed in the center thereof. Cladding is formed outside the connection portion. |
