PROBLEM TO BE SOLVED: To provide a detector which can be attached to the surface of a patient by simple operation without using a suction pump. SOLUTION: A body part 10 of a detector 1 is formed of conductive rubber in the form of a cup. A protruded part 11 is integrally formed on a top part of the body part 10, and a connection pin 3a for providing an electric signal for treatment is connected to the protruded part 11. As an opening end surface of the body part 10 is in contact with a surface K of a patient. the protruded part 11 is pressed from above till a skirt part 15 is elastically deformed to reduce an inner volume of the body part 10. As the opening end surface of the body part 10 is tightly applied to the surface K of the patient, pressure to the protruded part 11 is released, so negative pressure for suction is generated inside the body part 10 by elastic restoration action of the skirt part 15, thereby the body part 10, that is the detector 1, is strongly applied to the patient K by the negative pressure for suction.
