Provided is a production method of a sheet member, including a process of forming, by printing, a phosphorescent layer containing a phosphorescent material on a surface of a sheet-shaped substrate with a transmissive property, and a process of forming a reflection layer, by printing, including a reflective material to reflect light on a surface of at least either one of the substrate or the phosphorescent layer in such a manner that the reflection layer overlaps at least a part of the phosphorescent layer in a thickness direction of the substrate.
