Abstract
Capacitors, each of which is electrically connected to a capacitor which is the cell of the CMUT mounted in a chip and is used as a DC block capacitor for protecting an amplifying circuit, are formed as many as plural aligned channels in the chip. The capacitor is an electrostatic capacitance element which is not vibrated acoustically.
