PROBLEM TO BE SOLVED: To provide a cardiopulmonary function monitoring device capable of monitoring cardiopulmonary functions without contact with a human body.SOLUTION: A cardiopulmonary function monitoring device includes: a local oscillator 1 for generating a microwave; a transmit antenna 2 for transmitting the microwave generated by the local oscillator 1; a receive antenna 3 for receiving a reflection wave from a person being monitored; a mixer 4 for mixing the microwave generated by the local oscillator 1 and the reflection wave, and outputting a signal which is based on a difference between the microwave and the reflection wave; an A/D converter 6 for subjecting the signal output from the mixer 4 to A/D conversion; and a calculation control unit for subjecting the signal output from the A/D converter 6 to Fourier transformation, subjecting the signal after the Fourier transformation to filter processing, and calculating a heart rate and a respiration rate.
