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.
