摘要：
A roll-shaped thermosensitive recording material having a thermosensitive recording layer, which includes as main components an electron donating coloring agent, an electron accepting color developer and a binder resin and which is formed overlying a substrate, wherein the roll-shaped thermosensitive recording material has a variation (R) of thickness of in the lateral direction of not greater than 3 &mgr;m. Alternatively, the roll-shaped thermosensitive recording material has a difference in thickness between the left side and the right side in the lateral direction of not greater than 0.7 &mgr;m.
