Abstract

PURPOSE:To produce a microphone capable of preventing the specific instability owing to temperature changes by compession-bonding a high molecular piezoelecttric film which has been annealed for a fixed time after having been oriented in a uniaxial direction, to a curved frame in a state wherein tension is kept applied thereto.
