Abstract:
The recording medium includes: an absorbent substrate; and an ink receiving layer provided on the absorbent substrate. The dry coating amount of the ink receiving layer is 6.0 g/m2 or more to 11.0 g/m2 or less, arithmetic average roughness Ra1 (μm) of a surface of the absorbent substrate satisfies a relationship of Expression (1) below, arithmetic average roughness Ra1 and arithmetic average roughness Ra2 (μm) of a surface of the ink receiving layer satisfy a relationship of Expression (2) below, and an average length RSm1 (mm) of a roughness curve element of the surface of the absorbent substrate and an average length RSm2 (mm) of a roughness curve element of the surface of the ink receiving layer satisfy a relationship of Expression (3) below. Ra1≥5.0 μm (1) Ra2/Ra1≥0.87 (2) RSm2/RSm1≤1.40 (3)
