<P>PROBLEM TO BE SOLVED: To provide a composition for injection molding capable of manufacturing a compact that exhibits an excellent shape retention property during degreasing, and capable of manufacturing a high-quality sintered body with less deformation, loss, etc., the sintered body with high dimensional accuracy manufactured using the composition for injection molding, and a method for manufacturing the sintered body capable of efficiently manufacturing the sintered body. <P>SOLUTION: The composition for injection molding includes inorganic powder composed of at least one of a metal material and a ceramic material, and a binder containing polyacetal-based resin as a component A, unsaturated glycidyl group-containing polymer as a component B, and a lubricant as a component C. A compound 1 made by molding these has an inner layer 21 disposed so as to cover particles 2 of the inorganic powder and composed mainly of the component B, and an outer layer 22 located outside the inner layer 21 and composed mainly of the component A. <P>COPYRIGHT: (C)2013,JPO&INPIT |
