A joining method of a plastic product is provided to prevent product damage and to achieve clean appearance according to no contact between the plastic product and a joining device by adapting a high frequency joining method used in conventional metal joining, with bonding melt material of mixture of a plastic particle and a metal particle. A joining method of a plastic product comprises the steps of: injecting bonding melt material(6) of mixture of a small plastic particle(1) and metal particle(2) between both joining surfaces of the plastic products(7,8) to be joined; locating plastic products(9,10) at a place of the bonding melt material in a high frequency induction coil(12) of a high frequency melting device(11); and pressing the both joining surfaces of the plastic products to contact closely with each other, heating the metal particles in the bonding melt material at the both joining surfaces by the high frequency induced by the high frequency induction coil, and melting and joining the plastic particles and the joining surfaces by melting heat of the metal particles with operating the high frequency melting device for a necessary period.
