A load detector (100) includes: a beam-type load cell (21, 22) supported on a support base (11b, 12b) in a cantilever manner； and a placement part (30) connected to the beam-type load cell. The placement part has a placement plate (P30, P31, P33, P34, P35, P36) onto which a subject is placed, and a slope (SL) which is configured to guide the subject from a floor surface onto the placement plate. A forward end (SLT) of the slope is swingable about a first perpendicular axis perpendicular to the placement plate or a second perpendicular axis perpendicular to the slope, and/or is movable in a width direction of the placement plate.
