PROBLEM TO BE SOLVED: To beautifully bond even materials, which comprise a thermoplastic polymeric substance with a low melting point like a polyolefinic resin fiber, using a water insoluble heat-fusible resin. SOLUTION: A water insoluble heat-fusible resin 12 brought to a molten state by heating is applied to the upper and rear surfaces of a flexible sheet 11 constituted of a non-thermoplastic substance and the coated sheet is held between two materials 13, 14 having a planar shape to be bonded to the materials.
