A metal powder injection moldable composition which hardly causes debinding deformation is obtained. This composition consists of a metal powder and an organic binder. The components which constitute the organic binder are: a. polyoxymethylene having a Vicat softening temperature A>/=150 DEG C., b. polypropylene having a Vicat softening temperature B>/=130 DEG C., c. an organic compound whose viscosity at said Vicat softening temperature A ( DEG C.) is not more than 200 mPaxs, and d. a thermoplastic resin whose Vicat softening temperature is not higher than said B ( DEG C.). |
