Abstract
A heat conductive structure for a thermometer with a structure with temperature indication markings includes a probe structure with a thermal conductive surface. A temperature indication portion is disposed adjacent to the probe structure. A reversible temperature-sensitive color changing layer is formed on the temperature indication portion to overlap the structure of the temperature indication markings. The probe structure is adapted for sensing the thermal contact surface to conduct heat flow to the reversible temperature-sensitive color changing layer, producing a sensed temperature and a color changing zone of the reversible temperature-sensitive color changing layer in response to the sensed temperature thereby exhibiting a corresponding temperature value.
