The invention relates to a solid capacity microphone, which comprises: a liner (2), a upper capacitor pole plate (21), a lower capacitor pole plate (22), a capacitor medium film (23), and lead wires (221). Wherein, liner (2) has a lower capacitor pole plate (22) above it; the middle of liner (2) and the lower part of lower capacitor pole plate (22) have hollow chambers (1); the upper and lower capacitor pole plates (21, 22) are electrode films, while capacitor medium film (23) is filled between them to form the solid capacitor structure as conductive-medium-conductive structure; a conductive element (24) is inside the medium film (23); and the lead wires coat the hollow groove (24). The invention can be compatible with standard integrated circuit technique, with simple process and high sensitivity.
