PURPOSE:To make a drinking can heatable without hindrance such as can burning or the like irrespective of type of abutting part of the drink can by constituting a heating coil with a first heating coil to be situated in a bottom surface of the drink can at time of heating the drink can, and at least one or more second heating coils being connected to this first heating coil in series and situated in the can side. CONSTITUTION:In this device, there is provided with a heating coil that is constituted of a first heating coil 13 to be situated in the bottom surface of a drink can 2 at time of heating this can 2, and second heating coils 14-1 and 14-2 being separately installed in a can axial direction and a current flowing in adjacent coils comes to the same phase. And, an eddy current to be generated in the can 2 is dispersed and current density per unit area is lowered. With this constitution, even if an abutting part 11 of the drink can 2 is of an insulator such as a bonding agent or the like, partial can burning is preventable irrespective of the position of the abutting part 11.
