PROBLEM TO BE SOLVED: To provide a constant-weight cutting device capable of cutting even an elastic cylindrical food by a previously set prescribed weight in good accuracy by a simple measurement. SOLUTION: The constant-weight cutting device 10 cuts the elastic food K into individuals k having a constant weight. The constant-weight cutting device 10 is equipped with a shape-arranging means (a shape-arranging pulley 12 and a pressing pulley 13), a sensor 14, a cutting-controlling part 15 and a cutter 16. The shape-arranging means arranges the shape of the elastic food K so as to have a constant cross section. The sensor 14 measures the size h (t) corresponding to the cross section area of the elastic food having the shape arranged by the shape-arranging means. The cutting-controlling part 15 determines a cutting site CtXof the elastic food K based on the output from the sensor 14, the specific gravityρof the elastic food K, and the conveying speed U, and cuts the cutting site of the elastic food K by the cutter 16.
