    Abstract: Provided is a pressure measuring material having a substrate and a pressure-sensitive layer, wherein the pressure-sensitive layer contains a polymer matrix containing a polymer compound having a molecular weight of 1,000 or more, and microcapsules encapsulating an electron-donating dye precursor and a solvent, and an electron-accepting compound. The pressure-sensitive layer has a color development-inducing layer having the electron-accepting compound and the polymer matrix and a color-developing layer having the microcapsules. A thickness of the color-developing layer is equal to or less than ½ of a thickness of the color development-inducing layer.
