<p>Provided is a method of manufacturing composite magnetic material such that magnetic modification can be reliably carried out from the front face to the back face of a base material. The method of manufacturing composite magnetic material according to the present invention is provided with: a key-hole forming process for forming a key-hole through a base material that is formed from magnetic material or non-magnetic material, by melting the base material by heating, from the front face towards the back face thereof; and an element arranging process wherein an alloy element is arranged within a molten pool surrounding the key-hole. When the base material is made of magnetic material, the magnetism of the portion of the base material that was melted by the laser beam is weakened or de-magnetized, and when the base material is made of non-magnetic material, the portion of the base material that was melted by the laser beam is magnetized.</p> |
