PROBLEM TO BE SOLVED: To provide a biometric information detection device and a biometric information detection method capable of widely detecting biometric information, posture changes, movements, etc. of a watching target with a simple configuration. SOLUTION: A microwave transmitting unit that sends a microwave of a predetermined frequency to a space so as to pass near the measurement target, and a microwave that is transmitted from the microwave transmission unit and propagates near the measurement target. A microwave receiving unit that receives a certain passing wave, a demodulating unit that demodulates a passing wave receiving signal that is the received signal of the passing wave using the microwave signal from the microwave transmitting unit, and the demodulating unit The biological information measuring device is provided with an analysis unit that monitors the state of the measurement target by measuring the amplitude and phase of the output demodulated signal over time.
