A seat-occupancy state detection device includes: a seat occupancy sensor forming a pressure sensitive portion on a seat occupancy surface of a seat; a load sensor detecting a load applied to the seat occupancy surface; and a seat-occupancy state determination unit determining a seat occupancy state based on an ON/OFF state of the seat occupancy sensor and the load, wherein the seat-occupancy state determination unit includes a seat non-occupancy state determination section determining a seat non-occupancy state in a case where the seat occupancy sensor enters an OFF state and the load is equal to or lower than a first threshold value, and a threshold-value setting section setting a threshold value of the load, which is used in determination of the seat non-occupancy state, to a higher value, as duration increases after the seat occupancy sensor enters the OFF state.
