PROBLEM TO BE SOLVED: To provide a method for continuously extruding a metal powder, which provides an excellent bonding strength between an anterior extrusion material which has been previously extruded and a posterior extrusion material which has been subsequently extruded. SOLUTION: The method for continuously extruding the metal powder includes: a step of charging a heated metal powder 3 into a die 1 for extrusion having an extrusion aperture, in as a powder state; a first extrusion step of extruding the metal powder 3 in the die 1 by using an extrusion tool 4; a subsequent step to the first extrusion step, of charging the additional heated metal powder 6 in as the powder state onto a compressed body 5b of the metal powder which remains in the die 1 in a compressed state; and the second extrusion step of extruding the compressed body 5b and the additional metal powder 6 in the die 1 by using the extrusion tool 4.
