PROBLEM TO BE SOLVED: To provide an ear clinical thermometer, capable of ensuring accuracy within a wide environmental temperature range, by eliminating the influence due to short-term environmental temperature variation, eliminating work for calibration or permitting calibration extremely simplified than that of a thermopile system, and having indication without fluctuations due to the influence of the environmental temperature.SOLUTION: In a probe 20 of the ear clinical thermometer, a resin-made second high heat insulation member 220 is connected to the tip of a resin-made first heat insulating member 210 by a conventional connection means. The second high heat insulation member 220 is tapered, and a recessed surface 221 is formed at the tip. A protective cover 230 covers the first heat insulating member 210 and the second high heat insulation member 220. A thermistor lead thin line 240 is embedded in the first heat insulating member 210 and the second high heat insulation member 220. A tip-folding 241 is exposed at the recessed surface 221 of the second high heat insulation member 220 so as to be stretched. An ultra high-speed response thermistor 250 is mounted at approximately the center of the tip-folding part 241 of the thermistor lead thin line 240.COPYRIGHT: (C)2006,JPO&NCIPI【課題】 短時間の環境温度変化による影響を排除し、広い環境温度範囲内での精度保証が可能であり、校正作業なし、またはサーモパイル方式に比べて大幅に簡略化された校正が可能であり、環境温度の影響により示度がばらつかない耳式体温計を得ること。【解決手段】 耳式体温計のプローブ20は、樹脂製の第1断熱部材210の先端に樹脂製の第2高断熱部材220が慣用の連結手段によって接続される。第2高断熱部材220は、先細りのテーパが付けられ、先端に凹面221が形成される。保護カバー230が第1断熱部材210および第2高断熱部材220を覆う。サーミスタリード細線240が第1断熱部材210および第2高断熱部材220内に埋め込まれ、先端折返し部分241が第2高断熱部材220の凹面221に露出して張り渡される。サーミスタリード細線240の折返し部分241のほぼ中央に超高速応答サーミスタ250が装着される。【選択図】 図1
