The thermo reversible recording medium comprises a substrate and a thermo sensible layer. This thermo sensible layer is made of resin and organic lower molecular weight substance and can become transparent-state or opaque-state depending on temperature. The organic lower molecular weight substance is a linear hydrocarbon-containing compound having no carboxyl group (A) and a linear hydrocarbon-containing compound having no carboxyl group (B) having a melting point lower than the melting point of the linear hydrocarbon-containing compound having no carboxyl group (A) by 20° C. or more.
