Abstract: 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.gtoreq.150.degree. C.,b. polypropylene having a Vicat softening temperature B.gtoreq.130.degree. C.,c. an organic compound whose viscosity at said Vicat softening temperature A (.degree. C.) is not more than 200 mPa.multidot.s, andd. a thermoplastic resin whose Vicat softening temperature is not higher than said B (.degree. C.).
