Abstract
The present invention relates to a pressure-sensitive sheet having a function which can permanently conserve an indication showing different concentrations according to the intensity of an external pressure applied to pressure-sensitive paper. The pressure-sensitive sheet proposed by the present invention comprises a set of: a pressure-sensitive paper (10) having a surface to which ink (11) is applied; and a transparent film (20) which is disposed on the pressure-sensitive paper (10) and has a rear surface to which an adhesive agent (21) is applied.

A pressure-sensitive sheet comprising a set of:
- a pressure-sensitive paper (10) having a surface to which ink (11) is applied;
- a transparent film (20) that is disposed on top of the pressure-sensitive paper (10) and has a rear surface to which an adhesive (21) is applied,
- wherein the pressure-sensitive paper (10) and the transparent film (20) are overlapped to lie one on top of the other, so as to express the ink (11) of the pressure-sensitive paper (10) on the adhesive (21) of the transparent film (20) by applying pressure to a top surface of the transparent film (20).
