Abstract

PURPOSE:To make a capacitor substrate unnecessary, to reduce the cost of a component, and to improve assembling workability by forming a capacitor on an oscillation substrate integrally. CONSTITUTION:First and second oscillation electrode films 4 and 7 are formed on the oscillation substrate 2, respectively, and also, first-third capacitor electrode films 5a, 5b, and 10 are formed, and external derivation electrode films 12a, 12b and a pair of dielectric made coating substrate 3 having a ground electrode film 12c are superposed on both main planes of the oscillation substrate 2. In such a way, only two kinds of substrates are required, and it is possible to reduce the cost of the component and to improve the assembling workability.
