Quality control of product manufacturing is performed with a simple structure and, in addition, damage of a product when a production line is stopped is avoided. A preheating block approaches a circuit substrate having a predetermined length along a tape substrate from a predetermined position by gradual upward movements to carry out preheating and is then returned to the predetermined position, a main heating block arranged close to the preheating block is made to contact the circuit substrate on which the preheating has been carried out and which is transported in a predetermined tact to apply peak heating and is then restored to the predetermined position, and a cooling block accesses the circuit substrate to which the peak heating has been applied to cool the circuit substrate and is then returned to the predetermined position.
