There are provided an ion-conducting microparticle including an ion-dissociative group and exhibiting an affinity for a fluorine-containing resin, and a method of manufacturing the same, an ion-conducting composite including the ion-conducting microparticle, a membrane electrode assembly (MEA) including the ion-conducting composite as an electrolyte, and an electrochemical device such as a fuel cell. A reacting molecule 13, which includes, in only one end, a second reacting group 14 capable of being bonded to a first reacting group 12, and includes, in a main part and/or the other end, an atom group 5 having an affinity for a fluorine-containing resin, acts on a material microparticle 11 including an ion-dissociative group 3 and the first reacting group 12 on a surface of a base-material microparticle 2, and a reformed group 4, which is bonded at only one end to the surface of the base-material microparticle 2, and includes, in a main part and/or the other end, the atom group 5 having an affinity for a fluorine-containing resin, is introduced into the surface of the base-material microparticle 2 by a reaction between the first reacting group 12 and the second reacting group 14 to form an ion-conducting microparticle 1. |
