PROBLEM TO BE SOLVED: To solve a problem such that the cooling of medium to the moving plate of a stacking press is always performed for preventing thermal degradation of the packing inside a pressing cylinder due to heat conduction from a hot plate, which in turn the calorie by heating the hot plate becomes insufficient against the formation calorie of a stacking material by cooling the moving plate in this way. SOLUTION: In the stacking press in which a stacking material is inserted between heating plates and subjected to heating pressing, there are used a pressing ram which carries out relative displacement of a moving plate as against a fixed plate, a plurality of heating plates which are present between the moving plate and fixed plate, and a heating apparatus for regulating the temperature of a heating plate. In order to properly regulate the temperature of the moving plate heated by the heating plate, there is installed a solenoid valve to an external line for circulating medium to the internal passage of the moving plate, and also the temperature control is performed by comparing the detection temperature and preset temperature of the moving plate or medium, and actuating or stopping the solenoid valve.
