Abstract: A prepreg includes; sizing agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic compound (B) at least containing an aromatic epoxy compound (B1). The thermosetting resin composition includes a thermosetting resin (D) and a latent hardener (E), and optionally includes an additive (F) other than the thermosetting resin (D) and the latent hardener (E). The (a)/(b) ratio is within a predetermined range where (a) is the height of a component at a binding energy assigned to CHx, C—C, and C═C and (b) is the height of a component at a binding energy assigned to C—O in a C1s core spectrum of the surfaces of the sizing agent-coated carbon fibers analyzed by X-ray photoelectron spectroscopy.

Abstract: Sizing agent coated carbon fibers obtained by coating carbon fibers with a sizing agent comprising at least one of (A) to (C) in a total amount of 80 mass % or more with respect to the whole sizing agent, the carbon fibers each having a surface layer which has a thickness of 10 nm or larger and has an oxygen content of 4% or higher with respect to all the elements, wherein when the sizing agent coated carbon fibers are subjected three times to a 10-minute ultrasonic treatment in an acetone solvent, then the amount of the remaining sizing agent is 0.1-0.25 parts by mass per 100 parts by mass of the sizing agent coated carbon fibers. (A) At least one polymer selected from the group consisting of polyimides, polyetherimides, and polysulfones (B) A compound having a terminal unsaturated group and a polar group in the molecule (C) A polyether-type aliphatic epoxy compound and/or a polyol-type aliphatic epoxy compound which each have an epoxy equivalent of 250 g/eq or less and have two or more epoxy groups in the molecule
