Abstract: Provided is a production method that enables the production of a composite body of lithium titanate particles and a carbonaceous material, the composite body having excellent electrical characteristics and so on, and the composite body of lithium titanate particles and a carbonaceous material. A method for producing a composite body of lithium titanate particles and a carbonaceous material includes the steps of: preparing a raw material mixture using a titanium compound, a lithium compound, and an oligomer and/or raw material monomer of an alkali-soluble resin; and subjecting the raw material mixture to heat treatment under a non-oxidizing atmosphere to produce the composite body.
