PROBLEM TO BE SOLVED: To provide an induction heating cooker that makes an optical sensor substrate inconspicuous and is excellent in design.SOLUTION: An induction heating cooker includes a top plate 2 on which a heating target 300 is mounted, a heating coil 324 which is disposed below the top plate 2 and heats the heating target 300, an inverter circuit for supplying power to the heating coil, an optical sensor unit 20 having a thermopile 20b which is disposed below the top plate 2 and detects infrared ray radiated from the heating target 300, and an optical sensor substrate 20a on which the thermopile 20b is mounted, control means for controlling heating power of the heating coil based on an output signal from the optical sensor unit 20, and a cylindrical optical path 40 which is disposed below the top plate 2 and guides the infrared ray radiated from the heating target 300 to the thermopile 20b. The inner wall 40a of the optical path 40 is based on block color, and the upper surface 20d of the optical sensor substrate 20a has a darker similar color to the black color than the inner wall 40a of the optical path 40.SELECTED DRAWING: Figure 4 |
