Abstract: An electronic component includes a stack and first to third inductors. Area of a region obtained by perpendicularly projecting a first space including a first axis and surrounded by the first inductor onto an XZ plane is larger than area of a region obtained by perpendicularly projecting a second space including a second axis and surrounded by the second inductor onto a YZ plane. The third inductor is disposed such that a third axis does not intersect the first space but intersects the second space.

Abstract: A band-pass filter includes a first input/output port, a second input/output port, a first high-pass filter, a first low-pass filter, and a first stub resonator. The first stub resonator includes a first distributed constant line. The first low-pass filter is provided between the first input/output port and the first high-pass filter in the circuit configuration. The first distributed constant line has a first end connected to a first path connecting the first input/output port and the first low-pass filter, and a second end closest to a ground in the circuit configuration.
