1. An adhesion/peeling method, comprising:
adhering a first surface side of an electrically peelable adhesive sheet to a predetermined position of a fixation target object, wherein the electrically peelable adhesive sheet is formed of an electro-peeling adhesive having adhesiveness on the first surface side and a second surface side thereof, and the adhesiveness of the electro-peeling adhesive is lowered due to an input of a voltage;
adhering a first electrode of an adherend including the first electrode formed of a conductor to the second surface side of the electrically peelable adhesive sheet;
containing a liquid at the predetermined position of the fixation target object to temporarily form a second electrode with conductivity on a surface of the fixation target object, the liquid being impregnated into the fixation target; and
inputting a predetermined voltage between the first electrode and the second electrode to peel of the electrically peelable adhesive sheet from the fixation target object,
wherein the adherend is a sensor detecting elastic waves, and
the elastic waves transferred to the fixation target object are detected via the electrically peelable adhesive sheet adhered to a sensitive surface of the sensor.
