Provided is a shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof. Accordingly, the present invention is formed so as to include a plurality of split rolls ( 23 ) provided in a width direction of a rolling material (S); a table ( 13 ) which guides the rolling material (S) and which is rotatably supported; a fixing member ( 25 ) supported by the table ( 13 ); torque detectors ( 29 a , 29 b) for separately detecting loads acting on both ends of the split rolls ( 23 ) when the rolling material (S) comes in contact with the split roll ( 23 ) as moments; supporting arms ( 24 a , 24 b) of which one end rotatably supports the split roll ( 23 ) and the other end is supported by the fixing member ( 25 ) through the torque detectors ( 29 a , 29 b); a meandering amount computing unit ( 41 ) for computing a meandering amount of the rolling material using the moments detected by the torque detectors ( 29 a , 29 b), and a plate shape computing unit ( 42 ) for computing a plate shape of the rolling material (S) using the moments and the meandering amount.
