To provide an adhesive for thermal fusion bonding which, even when subjected to high-temperature thermal fusion bonding for a long time, gives an adhesive interlining with sufficient adhesive power.

The adhesive for thermal fusion bonding comprises an aqueous thermoplastic resin dispersion prepared by heating a thermoplastic resin to its softening point or higher and dispersing the softened thermoplastic resin in an aqueous medium and contains inorganic particles having a wt. average particle size of 0.001-20 μm. The adhesive is thermally fusion bonded to the surface of a base fabric, giving an adhesive cloth.
