To provide a means which can avoid problems such as precipitation due to the mixing of a plurality of raw material liquids and can simultaneously produce a structure in which the raw material liquids are combined in each of fibers, when the composite material is produced from the raw material liquids by an electrodeposition.

This electrodeposition apparatus is used for applying a voltage between a raw material liquid-supplying portion and a flied raw material-receiving portion to form an electric field in a space between both the portions, and supplying a raw material liquid from the raw material liquid-supplying portion to the flied raw material-receiving portion to form a structure at least partially containing the flied raw material on the flied raw material-receiving portion. In this apparatus, the raw material liquid-supplying portion has two or more liquid containers capable of receiving raw material liquids, a nozzle which has a liquid-passing relation to the two or more liquid containers and through which the raw material liquids introduced from the two or more liquid containers can pass in a mutually separated state, and liquid-pushing means for pushing out the raw material liquids in the two or more liquid containers through the nozzle.
