PURPOSE:To obtain a smooth bonded surface which has no stepped difference of dielectric films of multilayer structure by covering a heat softening substance on the surfaces to be bonded of the films when bonding the films, superposing the films, and applying a supersonic wave to the films while applying a pressure to the films from a supersonic horn. CONSTITUTION:When transfer type recording media each of which has a supporting layer 30 and a recording layer 22 made of polyethylene terephthalate films and a resistance layer 21 made of acrylic resin are bonded, the end portions to be bonded of the media are covered with the same acrylic resin film as the material of the layer 21 of the medium, are superposed, are placed on a lower bearer 2, a supersonic wave is applied while pressurizing the media from a supersonic horn 1, thereby bonding the media. In this manner, the smooth bonded surface which has no stepped difference of the media can be obtained, and clogging of toner or the like can be prevented. A further smooth bonded surface can also be obtained by providing a supersonic energy buffer material 25 between the bearer 2 and the media to be bonded. |
