<;P>;PROBLEM TO BE SOLVED: To easily measure a tympanic temperature and an outside air temperature for a long period of time. <;P>;SOLUTION: This ear insertion type thermometer measures the temperature of the external acoustic meatus 4 with a tympanic temperature measuring section 37 fixed at the tip of an external acoustic meatus insertion section 34 to be inserted into the external acoustic meatus 4, measures the outside air temperature with an outside air temperature measuring section 38 fixed at the tip of an extension section 35 extending in a distal direction from the auricle 2, and is configured to support the external acoustic meatus insertion section 34 and the extension section 35 to a base section 31 as a fitting section 30 and a retaining section 32 to easily measure the tympanic temperature and the outside air temperature for a long period of time. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
