PROBLEM TO BE SOLVED: To provide a film-formed product capable of making an adhesion mark inconspicuous by reducing the occurrence of interference of light even if fingerprint oils and fats or machine oil adheres to a surface. SOLUTION: The film-formed product is obtained by forming a transparent cured film, which has a composition wherein fine particles are uniformly dispersed in a film forming resin, on a surface exposed to the outside. Either one of the film forming resin and the fine particles has a refractive index smaller than the refractivce index (n) of fingerprint oils and fats or machine oil and the other one of them has a refractive index larger than the refractive index (n). The cured film is formed by adjusting the cured film so that the refractive index thereof substantially becomes (n). The occurrence of the interference of light between the cured films, which are substantially equal to fingerprint oils and fats or machine oil in refractive index, is reduced.
