Abstract
A compound for metal powder injection molding includes secondary particles in which first metal particles are bound to one another, and a matrix region including a binder and second metal particles whose constituent material is different from that of the first metal particles. It is preferred that in the secondary particles, the first metal particles are bound to one another through the binder. It is also preferred that the average particle diameter of the second metal particles is smaller than that of the first metal particles.
