Abstract
Provided is a means for fixing calcium phosphate onto the surface of a metal by a treatment method which uses no acid and produces less residue. A method of producing a calcium phosphate composite in which calcium phosphate is bonded to the surface of a base material, the method including a surface treatment step of bringing the surface of the base material into contact with a surface treating agent, and then into contact with a silane coupling agent, to surface treat the base material; a polymerization step of initiating, after the surface treatment step, polymerization of the silane coupling agent by means of a polymerization initiator; and a bonding step of bonding the silane coupling agent at the surface of the base material after the polymerization step, with calcium phosphate; wherein the base material is a metal, and the surface treating agent is ozone water.
