COMPOSITE ELECTRONIC COMPONENT FOR RESONANCE CIRCUIT, AND RESONANCE CIRCUIT DEVICE

摘要

A composite electronic component (10) for a resonance circuit is provided with a laminated member in which a piezoelectric resonance element (PR1) and a variable capacitor (120) are laminated and routing conductors are formed. An external connection terminal (1842) is provided on a mounting surface of the laminated member. The external connection terminal (1842) and a terminal conductor (121) of the variable capacitor (120) are connected by a meander-shaped conductor pattern. The meaner-shaped conductor pattern is composed of a via conductor (1842), a routing conductor (153), a via conductor (1742), a routing conductor (1841), and a via conductor (1741). The via conductor (1842), the routing conductor (153), and the via conductor (1742) are formed in a region where the piezoelectric resonance element (PR1) and the variable capacitor (120) are not in contact with each other in the laminated member.
