Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 圧電基板20の両面の中央部に互いに対向す るように振動電極22が形成され、厚み縦振動モードを 利用したチップ型圧電部品において、圧電基板20の厚 みをt 1 、圧電基板20の幅をW 1 および振動電極22 の直径をDとした場合、これらの値が、 0.080≦t 1 ≦0.350、0.20≦D≦1.5 0、2.2≦W 1 /D で示される範囲に設定されているチップ型圧電部品。 【効果】 リップルを発振領域(共振点と反共振点との 間)の外側に出すことが可能となり、共振点と反共振点 の中点としての発振周波数が設計値からずれることを阻 止することができる。 (57) [Summary] [Structure] In a chip-type piezoelectric component in which the vibrating electrodes 22 are formed in the central portions of both surfaces of the piezoelectric substrate 20 so as to face each other, the thickness of the piezoelectric substrate 20 is t. 1 , the width of the piezoelectric substrate 20 is W 1 and the vibration electrode 22 Where D is the diameter of 0.080 ≦ t 1 ≦ 0.350, 0.20 ≦ D ≦ 1.5 A chip-type piezoelectric component which is set in the range of 0, 2.2 ≦ W 1 / D. [Effect] The ripple can be output outside the oscillation region (between the resonance point and the anti-resonance point), and the oscillation frequency as the midpoint between the resonance point and the anti-resonance point can be prevented from deviating from the design value.
