Abstract: PROBLEM TO BE SOLVED: To provide a read-only optical recording medium having little change in characteristics of a metal reflection film due to temporal change and having durability. SOLUTION: The read-only optical recording medium 100 includes: a substrate 101; an information recording surface that stores information by combination of a land L and a pit P; and the metal reflection film 102 provided in contact with the information recording surface. In the read-only optical recording medium, the metal reflection film 102 is represented by Al 100-x-z X x Z z (x and z denote at%), X includes an element including at least Ti, Z includes an element including at least Fe, and x=1.0 to 3.0 and z=0.05 to 1.0 are satisfied.
