Although a weight part of an acceleration sensor chip fixed on a die pad is coated with a gelatinous resin part of low elasticity, the weight part is easily displaced by an external acceleration. Thus, an acceleration can be detected with accuracy. Furthermore, long-term reliability equal to those of regular resin packages is ensured because those portions of an acceleration sensor device which are not used for acceleration sensing are sealed with a resin part. |
