PROBLEM TO BE SOLVED: To provide hydride-coated Fe-Co soft magnetic alloy powder and its manufacturing method. SOLUTION: In the hydride-coated Fe-Co soft magnetic alloy powder, the surface of Fe-Co soft magnetic alloy powder of 10 to 150μm average particle size is coated with hydride of rare-earth elements including Y, Zr hydride, Ti hydride, Hf hydride, V hydride, Ta hydride or Pd hydride (hereinafter referred to as metal hydride). In the method for manufacturing the hydride-coated Fe-Co soft magnetic alloy powder, the surface of the Fe-Co soft magnetic alloy powder is coated with the metal hydride by a high-speed impact method or a binder method by using the Fe-Co soft magnetic alloy powder having 10 to 150μm average particle size and powder of the metal hydride having 1 to 10μm average particle size.
