PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a metallic composite powder, which does not contain substantially agglomerated particles or silica particles, has a uniform silica coating on the surface, and is useful for various applications as functional powder. SOLUTION: In the method for manufacturing the silica-coated metallic compound powder, drying a slurry containing colloidal silica with a silanol group on the surface and metallic powder with an average particle diameter of 0.5-500μm is dried under the conditions in which no irreversible agglomeration between silica colloids occurs, the obtained powder in a solvent in which colloidal silica can disperse is redispersed, and excess colloidal silica which does not contribute to the coating is classified and removed.
