Abstract

A high-frequency electronic component includes a multilayer body including a first input/output electrode, a second input/output electrode, and a third input/output electrode, and a first input/output path and a second input/output path. The first input/output path includes a first inductor and a first capacitor. The second input/output path includes a second inductor and the first capacitor. The first input/output electrode is located at a position deviated from a symmetric axis along a short-side direction of one main surface of the multilayer body. A distance from the first input/output electrode to a winding portion of the first inductor is larger than a distance from the first input/output electrode to a winding portion of the second inductor, and an inductance of the first inductor is larger than an inductance of the second inductor.
