An FM demodulation apparatus (200) includes: an analog-to-digital conversion unit (201) which converts a modulated analog signal into a digital signal; a quadrature conversion unit (202) which converts, into two mutually quadratic baseband signals, the digital signal converted by the analog-to-digital conversion unit (202); a band limiting unit (205) which limits a frequency component exceeding a possible maximum frequency of the modulated wave, in the two baseband signals converted by the quadrature conversion unit (202); a detecting unit (206) which obtains a demodulated signal from the two baseband signals that have been band-limited by the band limiting unit (205); and a pulse noise suppressing unit (204) which suppresses pulse noise included in the signals inputted to the band limiting unit (205).
