Electromechanical transducer device and analyte information acquiring apparatus
To suggest an electromechanical transducer device with a high S/N ratio, an electromechanical transducer device includes a first substrate; electromechanical transducer elements two-dimensionally arrayed on a front surface of the first substrate and configured to provide conversion between acoustic waves and electric signals; an electric wiring substrate that is a second substrate electrically connected with a back surface of the first substrate; a first acoustic matching layer provided between the first substrate and the second substrate; an acoustic attenuating member arranged on a back surface of the second substrate; and a second acoustic matching layer provided between the second substrate and the acoustic attenuating member.
