PURPOSE:To easily and securely measure mastication by providing a displacement detecting element and a holding means to adhere the displacement detecting element to the side part of a face. CONSTITUTION:A displacement detecting element 3 is provided in the side part of a face 2 of a checked person 1, whose mastication is measured and an output is given through a lead wire 4 to a processing means 5. Then, an operated processing result is displayed by a display means 6. When the displacement detecting element is pushed on the part of the masticatory muscle, the side part of the face 2 is suitable for the measurement of a masticating number or masticating force. The displacement detecting element 3 is fit to a supporting member 8 by a fitting means 7 and a holding means 9 is composed of this supporting means 8 and the fitting means 7. The fitting means 7, which is fit to one edge part 8a of the supporting means 8, has a housing 10 and an elastic body 11, which is charged in the housing, and the displacement detecting element 3 is held on the elastic body 11. A cover 12, which covers the outer circumference surface of the displacement detecting element 3 and one part of the housing 10, transmits the displacement in the side part of the face 2 to the displacement detecting element 3 without fail.
