Zusammenfassung:To provide a reversible recording medium capable of improving display quality, and an exterior member.SOLUTION: A reversible recording medium includes a support base and a recording layer provided on the support base and having recording and erasing states reversibly changed. When expressing an absorption spectrum in a visible region of the recording layer in the erasing state and an absorption spectrum in a visible region of the support base by L*a*b*, respectively, a color saturation difference (ΔC*) between the support base and the recording layer satisfies the relation expression (1).SELECTED DRAWING: Figure 1 【課題】表示品位を向上させることが可能な可逆性記録媒体および外装部材を提供する。【解決手段】本開示の一実施形態の可逆性記録媒体は、支持基体と、支持基体上に設けられると共に、記録状態および消去状態が可逆的に変化する記録層とを備えたものであり、支持基体と記録層との彩度差（ΔＣ＊）は、消去状態における記録層の可視領域での吸収スペクトルおよび支持基体の可視領域での吸収スペクトルをそれぞれＬ＊ａ＊ｂ＊で表わした場合、関係式（１）を満たす。【選択図】図１
