To provide an optical information recording medium on which visual information can be recorded on a label face by using a laser apparatus for recording and reading electronic information by irradiation with a low output laser without exerting e.g. thermal influence over electronic information recorded on the medium. The present invention provides an optical information recording medium 100 having such a structure that on a substrate 101 , an electronic information recording layer 102 , a reflective layer 103 formed in contact with the opposite side of the electronic information recording layer 102 from a side where a laser beam 107 enters, a protective layer 104 , a visual information recording layer 105 and an overcoat layer 106 constituting an outermost layer are laminated in this order, wherein the surface roughness of the outermost layer on the label face side is at most ½ of the wavelength (lambda) of a laser beam 108.
