In the method of manufacturing the electromechanical transducer, a first insulating layer is formed on a first substrate, a barrier wall is formed by removing a part of the first insulating layer, and a second insulating layer is formed on a region of the first substrate after the part of the first insulating layer has been removed. Next, a gap is formed by bonding a second substrate on the barrier wall, and a vibration film that is opposed to the second insulating layer via the gap is formed from the second substrate. In the forming of the barrier wall, a height on a gap side in a direction vertical to the first substrate becomes lower than a height of a center portion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing an electromechanical transducer","description":"Provided is a method of manufacturing an electromechanical transducer having a reduced variation in a breakdown strength caused by a variation in flatness of an insulating layer.
