A non-contact blood-pressure measuring device includes: an image acquiring section that acquires a skin image obtained by capturing skin of a user； a pulse-wave timing calculating section that calculates, as a pulse-wave timing, time information indicative of a time at which time-varying luminance in the skin image reaches a peak； a millimeter-wave acquiring section that acquires a signal of a radio wave reflected by the user； a heartbeat timing calculating section that calculates, as a heartbeat timing, time information indicative of a time at which a time-varying distance to the user obtained on the basis of the signal of the radio wave acquired by the millimeter-wave acquiring section reaches a peak； and a blood-pressure determining section that determines blood pressure of the user on the basis of a time difference between the pulse-wave timing and the heartbeat timing.
