  The invention provides a material for pressure measurement which utilizes a color forming reaction between a colorless electron-donating dye precursor and an electron-accepting compound to form color, and having a color density difference (ΔD) of 0.02 or more before and after pressurization at 0.05 MPa. When the colorless electron-donating dye precursor is included in microcapsules and the median diameter of the microcapsules on a volume basis is A μm, 5000 to 30000 microcapsules having a diameter of (A+5) μm or more are present per 2 cm×2 cm area.
