とする電子レンジの重量検出装置。 A support roller that supports the turntable and rotates with the bottom wall of the heating chamber is disposed within the heating chamber, and a piezoelectric transducer is disposed at the roller rotation locus of the bottom wall of the heating chamber that generates stress due to rotation of the support roller. In the weight detection device for a microwave oven, the weight of the object to be heated placed on the turntable is detected by detecting the voltage generated in the piezoelectric transducer when the support roller rotates. A weight detection device for a microwave oven, characterized in that the width of the top of the outer periphery of the roller is smaller than the width of the pivot portion.
