Abstract
An ear thermometer includes a probe including an infrared sensor unit for measuring a temperature of an eardrum of an ear of a temperature measurement target parson in a non-contact manner, the probe attached to an ear hole of the temperature measurement target parson. The probe includes a probe body inserted into the ear hole of the temperature measurement target parson, a housing for supporting the probe body; and an in-ear type earpiece attached to the probe body and abutting on an inside of the ear hole of the temperature measurement target person. The infrared sensor unit includes a first sensor and a second sensor arranged in the probe body and spaced apart by a predetermined distance along a direction substantially orthogonal to the eardrum when the probe body is inserted into the ear hole of the temperature measurement target person.
