The purpose of the present invention is to provide a heat-sensitive recording medium which hardly causes safety concerns such as endocrine disrupting chemicals, and is excellent in chromogenic properties and light resistance, and also excellent in heat resistance. A heat-sensitive recording medium () has a configuration in which a heat-sensitive recording layer () is layered on a substrate (). The heat-sensitive recording layer () comprises a color former, a non-phenol-based developer, and a non-phenol-based antioxidant. The non-phenol-based antioxidant comprises a phosphorus-based antioxidant. Preferably, the non-phenol-based developer comprises a compound represented by the following formula (1) and/or a compound represented by the following formula (2). (The symbols in the formulae (1) and (2) are as defined in the specification.)
