Abstract
A probe of an ear-type clinical thermometer 20 comprises a first heat insulation member 210 made of a resin material and a second high heat insulation member 220 made of a resin material that is connected to a distal end of the first heat insulation member 210 by conventional coupling means. The second high heat insulation member 220 is tapered forwardly and is provided on the distal end with a concave surface 221. A protection cover 230 sheathes the first heat insulation member 210 and second high heat insulation member 220. A thermistor fine lead wire 240 is embedded in the first heat insulation member 210 and second high heat insulation member 220 so that a turning end portion 241 of the wire 240 is bridged over the concave surface 221 of the second high heat insulation member 220 to be exposed above the concave surface 221. An ultrafast responsivity thermistor 250 is mounted substantially on a center of the turning end portion 241 of the thermistor fine lead wire 240.
