The clamping plate 10 is fixed to a substrate 2, and the joint portion 11b is heat-sealed to the clamping plate 10 via the fusion-bond layer 15 in a state in which the tube 11a of the molded article 11 covers the pipe P. Additionally, a waterproof rubber sheet 12 for covering the substrate 2 is joined to the joint portion 11b of the molded article 11. COPYRIGHT: (C)2009,JPO&INPIT
