Abstract
Disclosed is an acceleration sensor having a small variation in detection sensitivity, in which one end portion of an oscillation detecting element is fixed so that the free length thereof does not vary. Supporting resins 4a, 4b are formed in one end portion of the oscillation detecting element 3. With the oscillation detecting element being inserted into a through hole 2h of a holding member 2 provided in a case 1, the supporting resins 4a, 4b are in close contact with the inner periphery of the through hole 2h. As a result, the oscillation detecting element 3 is fixed to and held by the holding member 2.
Claims7
An acceleration sensor comprising an oscillation detecting element that includes a rectangular strip-shaped piezoelectric substrate and signal electrodes attached to both surfaces of the piezoelectric substrate, and a holding member for holding the oscillation detecting element, wherein
- the holding member is provided with a through hole into which the oscillation detecting element is inserted,
- one end portion of the oscillation detecting element is provided with a supporting resin, and
- the oscillation detecting element is held by the holding member with the oscillation detecting element being inserted in the through hole and the supporting resin being in close contact with an inner periphery of the through hole.
