PROBLEM TO BE SOLVED: To provide a high-frequency heating cooker capable of detecting an error when an erroneous kind of an antenna which rotates or moves around for irradiating microwaves in a heating chamber is fitted by mistake. SOLUTION: The high-frequency heating cooker includes, at least either on a ceiling part or on a floor part: an antenna 20a which rotates or moves around for irradiating microwaves in a heating chamber; and a rotation detecting unit 12 which emits light to a position parting from a rotation center or a round-movement center of the antenna 20a and receives the reflected light and detects the rotation or round movement of the antenna 20a, and on the reflecting face of the light emitted by the rotation detecting unit 12 of the antenna 20a, there are arranged one or a plurality of regions 22 having reflective power different from the reflecting face. The heating cooker further includes: a determining means for determining whether the number or the shape of the regions having different reflective power are the proscribed number or shape or not based on an output of the rotation detecting unit 12; and a display means of its determination content when the determining means determines that the number and the shape are not the prescribed ones.
