Claim 3:
4. The living body detection device according to claim 3, wherein,
when the at least one non-contact sensor is in the directional mode, the at least one non-contact sensor measures the detection area in a first state having a first directivity and in a second state having a second directivity that is different from the first directivity,
the receiver receives, from the at least one non-contact sensor, a first measurement result that is obtained in the first state and a second measurement result that is obtained in the second state,
the extraction circuit extracts a first biological signal from the first measurement result and extracts a second biological signal from the second measurement result,
the counting circuit counts a first number of living bodies based on the first biological signal and counts a second number of living bodies based on the second biological signal, and
the verification circuit verifies whether a sum of the first number of living bodies and the second number of living bodies is equal to the prescribed number.
