PROBLEM TO BE SOLVED: To provide a chip for detecting small mass related to the extraction electrode of an integrated chip for detecting the small mass for detecting the state of the reaction, which occurs on an exciting electrode by forming a ligand on the exciting electrode, as a change in mass and to easily inspect DNA. SOLUTION: In the chip constituted by forming the exciting electrodes to the upper and under surfaces of the recesses of a piezoelectric single crystal substrate equipped with a plurality of the recesses respectively separated at predetermined intervals and setting the electrodes on one sides of the recesses as reaction electrodes to form the ligand, which captures a reaction state, on the reaction electrodes, a grooved flow channel is formed to a part of the piezoelectric single crystal substrate forming the recesses and a reagent is injected from the flow channel.
