A recording medium includes a substrate and at least one ink-receiving layer, wherein an outermost ink-receiving layer of the recording medium contains inorganic particles, particles other than the inorganic particles, and a binder, the particles other than the inorganic particles have an average primary particle size of 30 nm or more and 100 nm or less, the outermost ink-receiving layer of the recording medium has a thickness of 5 µm or more, 60% or more and 90% or less of the particles other than the inorganic particles in the outermost ink-receiving layer of the recording medium are present in a region 500 nm or less below the outermost surface of the recording medium, and the area ratio of a region containing the particles other than the inorganic particles to the outermost surface of the recording medium is 30% or more and 80% or less. |
