To accurately determine bed-leaving even if a sleeping person softly slips out of a bed in a device for determination of bed-leaving to determine whether the sleeping person leaves a bed.
The device for determination of bed-leaving includes a determination section 44 that determines the bed-leaving of a sleeping person triggered by an amplitude of a bioinformation signal S2 falls below a bioinformation threshold and, when a state where the amplitude of the bioinformation signal S2 is less than the bioinformation threshold continues for a bed-leaving bioinformation determination time or more and at the same time a state where, immediately before the trigger, the amplitude of a body motion signal S1 exceeds a body motion threshold continues a bed-leaving body motion determination time or more, or if a cumulative time of the time when the amplitude of the bioinformation signal S2 falls below the bioinformation threshold during a detection period after the trigger continues a cumulative determination time or more, determining that the sleeping person leaves the bed.
