Abstract:
1. A piezoelectric vibration component comprising: a package having a space sealed by a resin adhesive which permits the entry of moisture and in which space there is moisture; a piezoelectric vibrating element accommodated in the sealed space of the package, wherein, when the volume of the piezoelectric vibrating element is Ve and the volume within the package obtained by subtraction of the volume Ve of the piezoelectric vibrator from the volume of the space of the package is Vp, where Se is the surface area of the piezoelectric vibrating element, Sp is the surface area of the space inside the package when the piezoelectric vibrating element is absent, and M is the maximum mass of moisture in μg/mm 3 at the use temperature T and 100% relative humidity and where A=7.5×T/(237.3+T).
