As an interior construction, a dismantlable adhesion method using induction heating (IH) and thermoplastic adhesive has been proposed. The method is called "the allover method". But when a distance between an induction coil for generating EMF and heated metal is existed considerably, the conventional induction coil couldn't heat the metal sufficiently. That is, heating characteristics of the metal depend on the distance. In this paper, a new heating coil with concentrated winding having ferrate core is experimented. From experiments, an electric equivalent circuit is deduced, and heating characteristics of heated metal at the distances are analyzed. The usefulness of concentrated winding coil is cleared by analyzed characteristics.
