Zusammenfassung:	To provide: composite electroconductive particles which suppress cracking and peeling of a metal film and by which excellent metal-film adhesive properties can be achieved; and a method for producing the composite electroconductive particles.SOLUTION: The composite electroconductive particles each comprise: a base particle 11; adhesive particulates 12 which are arranged on the surface of the base particle 11 and contain oxygen atoms; and electroconductive particulates 13 in contact with the adhesive particulates 12. The adhesive particulates 12 including oxygen atoms are arranged on the surface of the base particle 11 and the electroconductive particulates 13 are in contact with the adhesive particulates 12, so that the cracking and peeling of the metal film can be suppressed and excellent metal-film adhesive properties can be achieved.SELECTED DRAWING: Figure 1 【課題】金属膜の割れや剥がれを抑制し、金属膜の優れた密着性が得られる複合導電粒子、及び複合導電粒子の製造方法を提供する。【解決手段】母粒子１１と、母粒子１１の表面に配され、酸素原子を含む接着微粒子１２と、接着微粒子１２と接する導電微粒子１３とを備える。酸素原子を含む接着微粒子１２が母粒子１１の表面に配され、導電微粒子１３が接着微粒子１２に接することにより、金属膜の割れや剥がれを抑制し、金属膜の優れた密着性を得ることができる。【選択図】図１
