An optical component composite body is obtained in which there is no damage to the optical component even when it is bonded to a metal holder by solder or low melting point glass. The metal holder of the present invention is provided with a mounting portion protruding from one side of the main body and a grasping portion protruding from the other side of the main body. The mounting portion is provided with a plurality of protrusions formed in a comb tooth configuration. An optical component formed from alumina (Al₂O₃) is bonded by solder to a bonding surface of a protrusion, another optical component formed from LiNbO₃ is bonded by solder to a bonding surface of another protrusion, and a further optical component formed from YVO₄ is bonded by solder to a bonding surface of a further protrusion.
