Abstract
An acceleration detector comprising an acceleration transducer assembly disposed in a housing and including a piezoelectric element and an inertial weight. A relatively soft resilient filler material is applied around the acceleration transducer assembly for resiliently supporting the acceleration transducer assembly relative to the housing so that the inertial weight can move relative to the piezoelectric element when an acceleration is applied to the inertial weight. A relatively hard sealing material is applied on the resilient filler material for sealing and covering the relatively soft resilient filler material against the environment. The resilient filler material and the sealing material may be thermosetting resin.
