PROBLEM TO BE SOLVED: To provide a heating cooker comprising a weight sensor not affected by circumferential environmental change. SOLUTION: This heating cooker comprises a heating chamber 2, a table 4a mounted on a bottom face of the heating chamber 2 for loading a heated object 3, and the weight sensor 5 mounted on a lower part of the table 4a for detecting a weight of the heated object 3. This differential capacitance type weight sensor 5 is composed of at least one movable electrode 53 and at least two fixed electrodes 54a, 54b, and capacitances C1, C2 detected from a plurality of condensers 55a, 55b composed of the movable electrode 53 and the fixed electrodes 54a, 54b are compared to detect the weight of the heated object.
