PROBLEM TO BE SOLVED: To control heating temperature of an induction-heating coil and to ease installation work and to reduce cost. SOLUTION: An induction-heating cooker (rice cooker 1) is composed of an induction-heating coil 4 (4a and 4b), to heat a subject to be heated (inner pot 2), via non-conductive material (protecting frame 3), soft magnetic material and resin material. The induction-heating cooker is equipped with insulating magnetic shielding material 5 installed at the outer side of the induction-heating coil. In that case, the induction-heating coil 4 is wrap and gyre around at least one more round than in the case of installing a ferrite core, and at the same time, the magnetic shielding material 5 is formed and provided like plural sticks. These magnetic shielding materials 5 are attached to the non-conductive material part 3 in an asteriated form from the center of the induction-heating coil 4. |
