FIELD: instruments. SUBSTANCE: device has four dielectric film layers 1, 3, 9, 10 which are joined in packet. Perforated layer 9 serves as stiffening ring. Layer 10 is convex and shaped as diaphragm which is covered with layer of metal foil 11. Basic screen 2 and additional screen 3 serve for protection against electromagnetic noise. Capacitor plate 4 is generated on surface of layer 3. In course of manufacturing, layers of dielectric film are glued using given temperature, pressure mode during given time. When packet is assembled, diaphragm convex shape is provided by pressing film layer 10. EFFECT: increased reliability. 2 cl, 2 dwg
