摘要：
A recording medium includes, in this order, a substrate, a first ink receiving layer containing inorganic particles, polyvinyl alcohol and a boric acid compound, and a resin layer containing a resin. In the first ink receiving layer, hydrated alumina accounts for 70% by mass or more of the inorganic particles. In the recording medium, the ratio of the boric acid compound content to the polyvinyl alcohol content is 30% by mass or more.
