The present invention provides a molding plate which can flexibly change the shape of a raw material powder molding body in a mold in order to meet various user requirements, improve productivity, save raw materials and reduce waste. The molding plate is used for molding a raw material powder molded body in a device for manufacturing a quartz glass crucible, in which the device for manufacturing the quartz glass crucible is provided with a mold and a raw material powder supply unit, raw material powder supplied to the inner side of the mold is molded into the raw material powder molded body in a crucible shape, and the raw material powder molded body is melted. The molding plate is provided with a molding plate main body and an edge plate which is detachable relative to the molding plate main body, and the edge plate has a shape corresponding to the shape of the surface of the upper end part of the raw material powder molding body at a position opposite to the upper end part of the raw material powder molding body when the molding plate is arranged on the inner side of the mold.
