摘要： PROBLEM TO BE SOLVED: To obtain a heating cooker capable of performing a heating control to restrain an excessively high temperature of a heated object.SOLUTION: A pan temperature estimated value Tn is estimated by subtracting a top plate temperature correction value obtained by multiplying an output value of a top plate temperature detection section 25 with a second correction coefficient β from an infrared temperature correction value obtained by multiplying an output value of an infrared temperature detection section 24 with a first correction coefficient α. An overheat monitoring temperature Tem is estimated by subtracting the top plate temperature correction value from the infrared temperature correction value obtained by multiplying the output value of the infrared temperature detection section 24 with a third correction coefficient γ(γ>α). A heating coil 14 is controlled so that the pan temperature estimated value Tn becomes a heated object target value that is a temperature of a heated object corresponding to a target temperature set by an operation section 3. When the overheat monitoring temperature Tem exceeds a first overheat restraining threshold that is higher than the preset heated object target value, heating by the heating coil 14 is stopped or fire power is reduced.
