PURPOSE: To obtain the laminating device, short in the time of temperature rising, easy in laminating work and good in finishing by a method wherein the outer surfaces of a pair of pressing rollers are heated with a heat radiative lamp as a heating source.

CONSTITUTION: The heat radiation type lamps 15 for heating the outer surfaces of the pressing rollers 11 are arranged near the pair of pressing rollers 11 and heat rays from the lamps 15 are directed to the pressing rollers 11 effectively by reflecting plates 16. A laminated material of a card 20 on a transparent film 21, inserted between the pressing rollers 11 is pressed under being heated by the outer surfaces of the pressing rollers thereby bonding the transparent film to the surface of the card and the like by fusion.
