A recording medium includes a substrate and two or more ink receiving layers on each of a first surface and a second surface of the substrate. The ink receiving layers each contain a pigment and a binder. A 1 , A 2 , B 1 , and B 2 (nm) satisfy the relationships (1), (2), and (3), where A 1 is the peak of the pore radius distribution of the outermost ink receiving layer (2) on the first surface side, A 2 is the peak of the pore radius distribution of the ink receiving layer (3), B 1 is the peak of the pore radius distribution of the outermost ink receiving layer (4) on the second surface side, and B 2 is the peak of the pore radius distribution of the ink receiving layer (5). The arithmetic average roughness Ra specified in JIS B 0601 of each of the outermost ink receiving layers (2, 4) is 0.50 µm or more. |
