Abstract
A recording medium includes a base paper, a polymer layer disposed on the base paper, and an ink-receiving layer disposed on the polymer layer. The base paper has a thickness of 50 μm or more and 130 μm or less. The polymer layer has a thickness of 20 μm or more and 60 μm or less. The polymer layer has an arithmetic average surface roughness Ra1 of 0.12 μm or more and 0.18 μm or less. The polymer layer has a roughness curve element average length RSm of 0.01 mm or more and 0.20 mm or less. The recording medium has an arithmetic average surface roughness Ra2 of 0.13 μm or less.
