PROBLEM TO BE SOLVED: To provide a apparatus for manufacturing an extruded plate with an indentation pattern which enables easy alteration of the thickness of the extruded plate without replacing a mouthpiece or an embossing belt. SOLUTION: The apparatus 31 for manufacturing the extruded plate with the indentation pattern is equipped with the mouthpiece 37 for extruding a hydraulic material, an open part 43 formed by notching the upper edge of the mouthpiece, the embossing belt 45 having the indentation pattern formed and a presser roller 47 for bringing the embossing belt 45 into close contact with a raw plate 39 extruded from the mouthpiece 37, and the embossing belt 45 is brought into close contact with the surface of the raw plate 39 extruded from the mouthpiece 37, so as to transfer the indentation pattern onto the raw plate 39. In the apparatus, the embossing belt 45 is formed in the same width as the open part 43 and so supported as to be movable vertically in the direction of the thickness of the raw plate 39. Block bodies 53 different in thickness are removably provided at the opposite end parts 37b and 37c of the mouthpiece so as to close up a gap between the embossing belt 45 and the opposite end parts 37b and 37c of the mouthpiece which is brought about by different positions in the vertical move of the embossing belt 45.
