PURPOSE:The titled adhesive, obtained by adding a specific ferroelectric substance and specific ferromagnetic substance to a thermoplastic resin, suitable for using in high-frequency heat bonding and having high exothermic efficiency. CONSTITUTION:A high-frequency heating adhesive obtained by adding (B) a ferroelectric substance having a dielectric hysteresis loss in a high-frequency electromagnetic field, e.g. barium titanate, and (C) a ferromagnetic substance having a magnetic hysteresis loss in the high-frequency electromagnetic field, e.g. gamma-iron oxide, to (A) a thermoplastic resin. Preferably, the amounts of the components (B) and (C) based on 100pts.wt. component (A) are as follows; 10-150pts.wt. components (B) and (C) and >=10wt%, based on the total amount thereof, components (B) and (C) respectively.
