ABSTRACT:
In a chip-type piezoelectric resonance component, a piezo-resonator (3) is fixed onto a base substrate (2) and a cap member (4) is fixed to the base substrate (2) to enclose the piezo-resonator (3). The piezo-resonator (3) is provided with upper and lower surfaces having shorter and longer sides of lengths a and b at a ratio which is set in the range of .+-.10% about a value satisfying the following equation:
