Title: ELECTRONIC COMPONENT
Abstract:
An electronic component with a built-in resonant circuit, wherein the passband of signals is narrowed. An LC resonant circuit (LC1) is formed by a coil (L1) including coil parts (30a, 30b) oriented from an external electrode (14a) toward an external electrode (14d) while winding in the direction of the arrow A. An LC resonant circuit (LC2) is formed by a coil (L2) including coil parts (30c, 30d) oriented from an external electrode (14b) toward an external electrode (14c) while winding in the direction of the arrow A. An LC resonant circuit (LC3) is formed by a coil (L3) and a capacitor (C3). The coil (L3) includes coil parts (30e, 30f) oriented from the capacitor (C3) toward the external electrode (14d) while winding in the direction of the arrow B around the coil parts (30a to 30d).
