On an upper surface of a fixed substrate 22, a plurality of strap-shaped base electrodes 27 are arranged in parallel to each other. On each of the base electrodes 27, an electret 28 is formed. The electret 28 has a width wider than the width of each base electrode 27, and the electret 28 covers an exposed surface of the base electrode 27. A movable substrate 23 is disposed in parallel to and facing the surface of the fixed substrate 22 where the electrets 28 and others are formed. The movable substrate 23 is movable relatively to the fixed substrate 22. On a facing surface of the movable substrate 23, strip-shaped counter electrodes 32 are each formed so as to face each base electrode 27.

Selon l'invention, une pluralité d'électrodes de base en forme de bande (27) sont agencées parallèlement l'une à l'autre sur la surface supérieure d'un substrat fixe (22), et un électret (28) est formé sur chacune des électrodes de base (27). L'électret (28) présente une largeur supérieure à celle de l'électrode de base (27). L'électret (28) couvre la surface exposée de l'électrode de base (27). Un substrat mobile (23) est agencé pour faire face et être parallèle à la surface du substrat fixe (22) sur laquelle l'électret (28) est agencé. Le substrat mobile (23) peut être déplacé par rapport au substrat fixe (22). Le substrat mobile (23) présente une surface en vis-à-vis sur laquelle des électrodes en vis-à-vis en forme de bande (32) sont formées pour faire face aux électrodes de base (27), respectivement.
