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: A plurality of recesses, which are respectively separated at predetermined intervals, are provided to the upper and under surfaces of a piezoelectric single crystal substrate, the exciting electrodes are formed to the upper and under surfaces of the recesses of the piezoelectric single crystal substrate, the electrodes on one sides of the recesses are set to reaction electrodes to form the ligand, which captures a reaction state, on the reaction electrodes, one of the extraction electrodes of the formed exciting electrodes is led out to the counter surface sides of the recesses through the through-hole formed to the main side of the chip and a temperature control means is provided to the surface of the piezoelectric single crystal substrate on the extraction side.
