To prevent discoloration of heat-sensitive recording information when an opposite surface (rear surface) of a heat-sensitive recording layer of a heat-sensitive recording body is stamped with oil-based ink or written with an oil-based ink pen.SOLUTION: A heat-sensitive recording body has a heat-sensitive recording layer mainly containing a colorless or pale color electron-donating leuco dye and an electron-donating developer on a support, and has a back coat layer provided on an opposite surface to the heat-sensitive recording layer of the support, where the heat-sensitive recording layer contains a specific metal chelate-type color-developing component, and the back coat layer contains a water dispersion-based resin.SELECTED DRAWING: None 【課題】感熱記録体の感熱記録層の反対面（裏面）に油性インキを用いてスタンプ又はペン書きした場合の感熱記録情報の退色を防止する。【解決手段】支持体上に、無色ないし淡色の電子供与性ロイコ染料及び電子受容性顕色剤を主成分として含有する感熱記録層を設け、該支持体の該感熱記録層とは反対面上にバックコート層を設けた感熱記録体であって、この感熱記録層が特定の金属キレート型発色成分を含有し、このバックコート層が水分散系樹脂を含有する感熱記録体である。【選択図】なし
