A powder compression molding machine includes a downward spray portion that sprays a lubricant toward an inner circumferential surface of a die bore and a tip face of a tip of a lower punch, an upward spray portion that sprays the lubricant toward a tip face of the tip of the upper punch, a first lubricant flow passage through which the lubricant supplied from a lubricant supply device externally provided is fed to the downward spray portion, and a second lubricant flow passage through which the lubricant supplied from the lubricant supply device externally provided is fed to the upward spray portion. A small-diameter region of which an inner diameter is made smaller than that of the first lubricant flow passage is provided at a part of the second lubricant flow passage.
