ことを特徴とするホツトプレス装置。 The die is equipped with a ram that presses the sample filled inside the die, and a drive source whose tip end is connected to the proximal end of the ram and drives the ram in the axial direction. In a hot press device that produces a sintered body by pressing the specimen, the strain generated in the longitudinal direction when the ram presses the sample is applied between the base end of the ram and the tip of the drive source. A plurality of strain detectors for detecting the strain are interposed at predetermined intervals on the outer peripheral edge of the proximal end surface of the ram, and a control device is provided for controlling the drive source based on the detection results of the strain detectors. A hot press device characterized by:
