ABSTRACT:
A platinum temperature sensor showing excellent sensitivity to heat. The sensor comprises an insulating substrate having a support portion at one end of the substrate. A heat-generating portion is formed by a platinum film circuit at the other end of the substrate. A coating made from a material having a low thermal conductivity is formed on the support portion of the insulating substrate to suppress dissipation of heat from the support portion. A first heat-insulating gap is created between an end portion of the platinum film circuit and the heat-generating portion. A second heat-insulating gap is created between the platinum film circuit and the coating.
