The present invention provides a method for manufacturing a matte coating film in which the matting agent does not fall off even if the coating film deteriorates. [Solution] A method for producing a matte coating film comprising the steps of (I) forming a coating film of an excimer laser photocurable matte coating agent on a substrate, (II) irradiating the coating film with ultraviolet light, (III) irradiating the coating film with excimer laser light, and (IV) irradiating the coating film with ultraviolet light or an electron beam, wherein the excimer laser photocurable matte coating agent contains (meth)acrylate, a photopolymerization initiator, and particles A having an average particle size of 1 nm to 10.0 μm, and the particles A are contained in an amount of 0.1 to 5% by mass relative to the nonvolatile components of the coating agent; and a matte coating agent used in the production method.
