Abstract
An annealing method according to the present invention is an annealing method of annealing a molded body (1) which is molded from a molding material in a molding step, and the method includes the steps of: (I) releasing stress from the molded body (1) by heating the molded body (1); and (II) correcting a warp of the molded body (1), by simultaneously heating the molded body (1) and applying a load to the molded body (1). This achieves an annealing method which makes it possible to obtain a molded body that is free from residual stress and distortion.
