An electronic component includes a common port, a first signal port that selectively passes a first signal of a frequency within a first passband, a second signal port that selectively passes a second signal of a frequency within a second passband higher than the first passband, a first resonator provided between the common port and the first signal port in a circuit configuration, a second resonator provided between the common port and the second signal port in the circuit configuration, a stack, and a shield that covers a part of a surface of the stack. The shield includes a specific portion opposed to both the first and second resonators. A distance between the second resonator and the specific portion is greater than a distance between the first resonator and the specific portion.

Multilayer electronic component

A multilayer filter includes: an element body formed by laminating a plurality of insulator layers; a first inductor and a second inductor; and a wall portion disposed between the first inductor and the second inductor and grounded, wherein at least the second inductor is a vertical winding type inductor of which a winding axis extends in a direction orthogonal to a laminating direction in which the plurality of insulator layers are laminated, a penetrating portion penetrating in a facing direction in which the first inductor and the second inductor face each other is formed in the wall portion, and a size of the penetrating portion in the laminating direction is larger than a size of one insulator layer.
