Abstract
A process for producing a capacitive electromechanical conversion device by bonding together a substrate and a membrane member to form a cavity sealed between the substrate and the membrane member, the process for producing a capacitive electromechanical conversion device comprises the steps of: providing a gas release path penetrating from a bonded interface between the substrate and the membrane member to the outside, and forming the cavity by bonding the membrane member with the substrate with the gas release path provided; the gas release path being provided at a location where the path does not communicate with the cavity.

A process for producing a capacitive electromechanical conversion device by bonding together a substrate and a membrane member to form a cavity sealed between the substrate and the membrane member, the process for producing a capacitive electromechanical conversion device comprising the steps of:
- providing a gas release path penetrating from a bonded interface between the substrate and the membrane member to the outside, and
- forming the cavity by bonding the membrane member with the substrate with the gas release path provided;
- the gas release path being provided at a location where the path does not communicate with the cavity.
A capacitive electromechanical conversion device obtained by bonding together a substrate and a membrane member to form a cavity sealed between the substrate and the membrane member,
- characterized in that a gas release path penetrating from a bonded interface between the substrate and the membrane member to the outside and not communicating with the cavity is provided in at least one of the substrate and the membrane member.
