A shape detection device and a shape detection method capable of accurately detecting the meandering of a strip. The shape detection device comprises a plurality of split rolls (23) installed in the lateral direction of a rolled material (S), a table (13) guiding the rolled material (S) and supported rotatably, a fixed member (25) supported on the table (13), torque detectors (29a, 29b) individually detecting, as moments, loads acting on both ends of the split rolls (23) when the rolled material (S) is brought into contact with the split rolls (23), support arms (24a, 24b) rotatably supporting the split rolls (23) at their one ends and supported, at their other ends, on the fixed member (25) through the torque detectors (29a, 29b), a meandering amount calculator (41) calculating the meandering amount of the rolled material (S) based on the moments detected by the torque detectors (29a, 29b), and a plate shape calculator (42) calculating the plate shape of the rolled material (S) based on the moments and the meandering amount.
