PROBLEM TO BE SOLVED: To provide a sticking type device capable of surely determining whether or not a sticking type device is in contact with a living body, particularly even in a state of being slightly floating from the surface of the living body. SOLUTION: The stick-on type deep body thermometer 1 has a light emitting unit 45 that emits detection light, a first scattering unit 603a that scatters the detection light transmitted through a translucent lower exterior body 20, and adhesiveness and light transmission. The detection light that has the property and is attached to the lower exterior body 20 and propagates in the first adhesive layer 601 and the first adhesive layer 601 to which the detection light scattered by the first scattering unit 603a is incident. The second scattering unit 603b that scatters the light, the light receiving unit 46 that receives the detection light scattered by the second scattering unit 603b and transmitted through the lower exterior body 20, and the amount of the detected light received is less than a predetermined value. In some cases, it is determined that the stick-on deep thermometer 1 is in contact with the surface of the living body, and when the amount of light received is equal to or greater than a predetermined value, it is determined that the stick-on deep thermometer 1 is not in contact with the surface of the living body. It is provided with a state determination unit 432.
