Abstract
A temperature indicating material of the present invention includes at least an electron donating compound, an electron accepting compound, a reversible material causing reversible transformation between crystal and amorphous states, or reversible transformation between phase separation and non-phase-separation, with respect to a part or all of the composition system; and a temperature characteristic controller having a solid-state in room temperature and at least a part of the temperature characteristic controller dissolves in the electron accepting compound, the reversible material, or the electron accepting compound and the reversible material so as to change the speed of the reversible transformation between crystal and amorphous, or speed of the reversible transformation between phase separation and non-phase-separation, with respect to the composition system, by its reversible transformation between crystal and amorphous states, or the speed of the reversible transformation between phase separation and non-phase separation.
