Classification: CPC G  A | IPC A  G

Claim 8:
9. A sticking-type deep body thermometer comprising:
a thermometer body;
a sticking member having an adhesive property on a bottom surface of thermometer body;
a first thermal resistor having a predetermined thermal resistance and disposed substantially parallel to the sticking member;
a first temperature sensor configured to detect a first temperature at a first surface of the first thermal resistor adjacent to the sticking member;
a second temperature sensor configured to detect a second temperature at a second surface of the first thermal resistor opposite the first surface;
a deep body temperature detection circuit configured to estimate a deep body temperature based on the first temperature and the second temperature; and
an attachment/detachment sensor configured to detect attachment and detachment of the sticking-type deep body thermometer, wherein the attachment/detachment sensor determines that attachment or detachment of the sticking-type deep body thermometer has occurred when, within a predetermined time, an absolute value of a temperature rate of change of the first temperature becomes greater than or equal to a second threshold value and an absolute value of a temperature rate of change of the second temperature becomes greater than or equal to a third threshold value.
