Abstract (in Japanese) (See Japanese page) 
(in English) We have developed a low-noise, high-sensitivity microphone with a wide frequency range for sound recording, with the aim of high quality archiving of the broadcasting material, as well as of their use to new recording media covering wide frequency range such as SACD or DVD-AUDIO. The proposed microphone has a novel design in which the frequency range is expanded in two ways, using both the scattering and the resonance of the microphone actively. As a result an omnidirectional electrostatic microphone has been developed, which picks up sounds of up to 100 kHz with low noise.
