The purpose of the present disclosure is to provide a heat sensitive sheet having an excellent wearing feeling both in an initial state and in use. This heat sensitive sheet has the following configuration. This heat sensitive sheet (1) includes a liquid-holding, liquid-permeable skin-contacting sheet (7), and a liquid-impermeable clothing-contacting sheet (11), and has a thickness direction (T). The heat sensitive sheet (1) has a heat sensitive layer (17) including a heat sensitive liquid composition which includes a heat sensitive agent activating a TRP channel of mammals and a solvent, and does not have a heat generating agent. The heat sensitive sheet (1) is characterized by having a stiffness change rate of 4.0 or less in a predetermined direction within a heat sensitive layer overlap region which overlaps the heat sensitive layer (17) in the thickness direction (T), wherein the stiffness change rate is the ratio of 3h stiffness to 0h stiffness. |
