A thermosensitive recording material is provided to secure excellent stampability, to prevent sticking, and to reduce the decrease in image density caused by image shielding by a protective layer. The thermosensitive recording material includes a protective layer, a thermosensitive recording layer, and a base formed in order. The thermosensitive recording layer shows the color by heat. The protective layer contains binder resin and an inorganic filler. The mean volume diameter of the inorganic filler is 0.6~5.0 micron meters. The inorganic filler is added about 150~400wt.% for the binder resin. The protective layer contains cross-linked polymethylmethacrylate particle with the mean volume diameter of 1.0~8.0 micron meters, about 5~75wt.% for the binder resin. The polymethylmethacrylate particle is porous. The inorganic filler is agglomerate.
