A method for manufacturing a glass-like carbon molded body is provided which can obtain an excellent glass-like carbon molded body without cracks from a thermosetting resin molded body having a large thickness exceeding, for example, 10 mm, unlike in the conventional method in which an upper limit of the resin molded body has been, for example, 7 mm, even at the rate of temperature increase that is industrially practical considering the productivity at a carbonization step of heating the thermosetting resin molded body when manufacturing the glass-like carbon molded body. The method for manufacturing a glass-like carbon molded body comprises a step of carbonizing a thermosetting resin molded body by heating the molded body in inert atmosphere. The thermosetting resin molded body has one or more opened vent holes on a surface thereof, and satisfies the following formula, in which r (mm) is either a distance from an arbitrary point inside the thermosetting resin molded body to an outer surface thereof, or a distance from the arbitrary point to a surface of the vent hole, whichever is shorter, and x (° C./h) is an average rate of temperature increase in a range of 400 to 600° C. at the carbonization step: r<(8.0-x.a)/2, where a=1 (mm.h/° C.). |
