1. An electronic thermometer comprising:
- a hollow probe including a temperature measuring unit having a temperature sensor for sensing a temperature at the longitudinal end of said hollow probe;
an electrode arranged in a hollow of said probe without being exposed to an outside of said probe and located near said temperature sensor; and
a determining unit for determining whether said temperature measuring unit is in appropriate contact with a measurement target portion of a user or not, based on a change in electrostatic capacity sensed using said electrode.

Abstract
An electronic thermometer includes a hollow probe provided at its longitudinal tip with a temperature measuring unit having a temperature sensor for sensing a temperature, electrodes neighboring to the temperature sensor and arranged in the hollow of the probe, and a determining unit for determining whether temperature measuring unit is in appropriate contact with a measurement target portion of a user or not, based on a change in electrostatic capacity sensed using the electrodes.
