ELECTROMECHANICAL CONVERSION DEVICE

Title:

ELECTROMECHANICAL CONVERSION DEVICE

Document Type and Number:

Japanese Patent JP2013229829

Kind Code:

A

Abstract:

To provide an electromechanical conversion device capable of reducing an unnecessary signal, noise, and the like in a received signal due to reflection of an acoustic wave by wiring.

On a substrate 100 of the electromechanical conversion device, an electromechanical conversion element 101 including at least one cell being a capacitive micromachined ultrasonic transducer or the like and wiring 102 which is connected to the electromechanical conversion element 101 and transmits at least an electric signal of a received acoustic wave are provided. An attenuation layer 301 for attenuating an acoustic wave is provided on the wiring 102.
