    摘要: In this high speed response type temperature sensor, a base body member is formed as a hollow tube with one closed end and one open end, and a temperature sensitive sensor layer is formed over at least part of its external surface. An electrode layer is arranged at at least a part of the periphery of the open end of the base body member, in contact with a part of the temperature sensitive sensor layer, and a protective cover layer is formed over at least a part of the sensor layer. Thus, since this sensor layer is formed on the external surface of the hollow tubular base body member, the opposing and contacting area between the sensor layer and the object whose temperature is to be measured becomes relatively large, and the distance therebetween is also reduced, so that the efficiency of heat conduction from the object to the sensor layer is greatly improved. Because the base body member is hollow, also, the overall heat capacity is greatly reduced. Accordingly, good and quick response of this temperature sensor are obtained, and accuracy is improved. Further, this sensor is relatively easy and cheap to manufacture.
