Abstract
(EN)
Disclosed is an electret which comprises a first region and a second region. The polarization direction of the first region along the thickness direction is in a first direction. The polarization direction of the second region along the thickness direction is in a second direction that is opposite to the first direction. The first region and the second region are provided adjacent to each other in a main surface direction that is parallel to a main surface, which is a surface perpendicular to the thickness direction.
(FR)
L'invention concerne un électret qui comprend une première région et une seconde région. La direction de polarisation de la première région dans la direction de l'épaisseur constitue une première direction. La direction de polarisation de la seconde région dans la direction de l'épaisseur constitue une seconde direction, opposée à la première direction. La première région et la seconde région sont adjacentes dans une direction de la surface principale qui est parallèle à la surface principale, qui est une surface perpendiculaire à la direction de l'épaisseur.
(JA)
 エレクトレットは、第一の領域と第二の領域とを有している。第一の領域は、厚さ方向に沿った分極方向が第一の方向となる領域である。第二の領域は、厚さ方向に沿った分極方向が第一の方向と反対の第二の方向となる領域である。第一の領域と第二の領域とは、厚さ方向と直交する表面である主面と平行な方向である主面方向に沿って、互いに隣接するように設けられている。
