PURPOSE:To correct continuously a bend of a printed circuit board in a short period of time, by heating and cooling the printed circuit board having a bend while pressurizing the same between metallic belts. CONSTITUTION:A printed circuit board having a bend is pressurized between metallic belts provided with a heating part and cooling part. Heating temperature is 140-170 deg.C, cooling temperature is a normal temperature -50 deg.C and pressure is 1-50 kg/cm<2>. As heating/cooling is performed while pressurizing, correction of the bend can be performed in a short period of time and the correction process can be incorporated into a continuous process.
