In forming a molded member (30) by insert molding, a porous member (10) and a cylindrical member (20) fitted on a peripheral edge of the porous member (10) are set in a die (40); and the molded member (30) is formed with the molded member (30) out of contact with the porous member (10) and with the molded member (30) in close contact with an outer surface of the cylindrical member (20) by the insert molding. Therefore a landed position (first landed surface (45A), second landed surface (45B)) of the die (40) is set on the outer surface of the cylindrical member (20). Thus there is no fear that liquid resin penetrates into the pores of the porous member (10) in the insert molding. Thereby by the insert molding, it is possible to form the molded member (30) holding the porous member (10). |
