PURPOSE: To obtain excellent bonding force by being heated to comparatively low temperature and for short period of time and pressurized under the condition that surfaces to be bonded are brought into close contact with each other by a method wherein the surface of metal plate is coated with a paint film containing a water-soluble or water-dispersible thermoplastic resin having a reactive functional group and a crosslinker. CONSTITUTION: This heat-sensitive adherent resin coated metal plate is obtained by coating the surface of the metal plate with a paint film containing a water- soluble or water-dispersible thermoplastic resin A having a reactive functional group and a crosslinker B and then dried under the temperature condition that no crosslinking reaction develops between the thermoplastic resin A and the crosslinker B. In this case, the thermoplastic resin A to be employed is one or two and more among a polyethylene-based resin, a polyester-based resin and a polyurethane-based resin having a functional group, which reacts with a melamine resin or with an isocyanate group. Further, the crosslinker B is a melamine resin having an active methylol group or blocked isocyanate group- containing compound.
