PROBLEM TO BE SOLVED: To provide a heating cooker having uniformly good resolution of a temperature range to be measured without requiring an amplification rate to be switched and complicating circuit construction. SOLUTION: An infrared detecting element 6 detects an infrared ray emitted from a heated object to detect the temperature of the heated object. It outputs an element signal V6 to a control circuit 7 and an amplification circuit 8. The amplification circuit 8 amplifies the output of the infrared detecting element 6 and gives an amplification signal V8 to the control circuit 7. The control circuit 7 uses one or both of the element signal V6 output by the infrared detecting element 6 and the amplification signal V8 output by the amplification circuit 8 for heating control.
