pushed inside. On the other hand, a plurality of reinforcing materials (4), which are arranged in advance at approximately equal intervals and in contact with all the inner walls of the die (1) by cutting the reinforcing material guides (3), are actuated by a drive device (9). The pressing member (5) pushes the inorganic composition extruded from the die (1), that is, the inorganic molded body (7), in synchronization with the extrusion speed. In this way, the mutual relationship between the inorganic composition (11) and the plurality of reinforcing materials (4) is maintained constant, and the inorganic molded body (7) is extruded in front of the die (1).
