Abstract: An electronic component includes a first inductor, a second inductor, and a shield structure. Each of the first inductor and the second inductor includes a plurality of inductor conductor layers. The plurality of inductor conductor layers include a first conductor layer closest to a first surface of a stack and a second conductor layer closest to a second surface of the stack. The shield structure is arranged between the first inductor and the second inductor when viewed in a stacking direction, and is arranged between the second conductor layer of each of the first inductor and the second inductor and the first surface of the stack.

Abstract: Each of a plurality of resonators of a filter device is wound around an axis orthogonal to a stacking direction of a plurality of dielectric layers of a stack and is arranged in a manner that an opening of each of the resonators faces one or more openings of one or two other resonators. The plurality of resonators include a first resonator and a second resonator adjacent to each other in a circuit configuration. Each of the first resonator and the second resonator includes a first portion and a second portion arranged with a certain distance in a direction parallel to the axis. The second portion of the first resonator and the first portion of the second resonator are adjacent to each other.

Abstract: A filter device includes a plurality of resonators and a stack. The plurality of resonators include a first parallel resonator and a first serial resonator. The first parallel resonator includes a conductor structure wound around an axis extending in a direction orthogonal to a stacking direction. The first serial resonator includes a conductor layer wound around an axis extending in a direction parallel to the stacking direction. The conductor layer includes three portions each located between a corresponding one of three side surfaces and at least part of the conductor structure when seen in the stacking direction.

Abstract: A band-pass filter includes a first port, a second port, first to third high-pass filters provided between the first port and the second port in this order from a first-port side in a circuit configuration, and a low-pass filter provided between the second high-pass filter and the third high-pass filter in the circuit configuration. Each of the first to third high-pass filters forms an attenuation pole on a low-pass side of the passband. A frequency of the attenuation pole formed by the second high-pass filter is higher than a frequency of the attenuation pole formed by each of the first and third high-pass filters.
