Pressure measurement plate set and pressure measurement method

Abstract

The invention relates to a device (10) for pressure measurement in which deformation of the support, reduction in the resolution of the pressure distribution image, and contamination of the object can be prevented in the case where pressure measurement is performed under high temperature conditions. In addition, the invention relates to a method for pressure measurement. The set of plates used for measuring pressure according to the light cover includes: the first plate (16) which includes the first support base (12) and the first layer (14) arranged on the first support base, the first layer includes the fins (13) which enclose the coloring agent; the second plate (22) which includes the second support base (18) and the second layer (20) arranged on the second support base, the second layer includes the coloring agent; and protective film (40), wherein the protective film is a plastic film or paper, a plastic film with a glass transition temperature of 100°C or higher or without a glass transition temperature, and the thickness TI of the first support, the thickness T2 of the second support, and the thickness 13 of the protective film satisfy all of the given conditions from (a) to (d) are determined.
