PROBLEM TO BE SOLVED: To provide a method for preparation wherein there is no possibility of falling-down and flattening of a raising material on a raised face and therefore, after integral molding, a work for recovering raised part of the raising material is completely unnecessary in a method for integral molding wherein molding of a base molded article and binding of the raising material are simultaneously performed. SOLUTION: In this method for preparing, the raising face 13 of a raising material 12 is arranged so as to be brought into contact with the mold face 21S of one of the freely opening/closing molds 20 and a molten resin material P as a base material is introduced into the molds to form the material into a specified base material shape. In addition, the mold face 21S with which the raising face 13 of the raising material 12 is arranged so as to be brought into contact is retreated by a height (v) of raising of the raising face to perform molding.
