Abstract:
(EN) A porous support (20) is provided with a base material (30), a supporting layer (32), and a topmost layer (33). The supporting layer (32) is disposed between the base material (30) and the topmost layer (33), and is in contact with the topmost layer (33). The ratio (A/B), i.e., the ratio of the porosity (A) of the topmost layer 33 to the porosity (B) of the supporting layer (32), is 1.08 or higher. The ratio (C/D), i.e., the ratio of the thickness (C) of the topmost layer (33) to the thickness (D) of the supporting layer (32), is 0.9 or smaller.
(FR) La présente invention concerne un support poreux (20) qui est pourvu d'un matériau de base (30), d'une couche de support (32) et d'une couche supérieure (33). La couche de support (32) est disposée entre le matériau de base (30) et la couche supérieure (33), et est en contact avec la couche supérieure (33). Le rapport (A/B), c'est-à-dire le rapport de la porosité (A) de la couche supérieure (33) à la porosité (B) de la couche de support (32), est de 1,08 ou plus. Le rapport (C/D), c'est-à-dire le rapport de l'épaisseur (C) de la couche supérieure (33) à l'épaisseur (D) de la couche de support (32), est de 0,9 ou moins.
(JA) 多孔質支持体(20)は、基材(30)と、支持層(32)と、最表層(33)とを備える。支持層(32)は、基材(30)と最表層(33)の間に配置され、最表層(33)に接する。支持層(32)の気孔率(B)に対する最表層33の気孔率(A)の比(A/B)は、1.08以上である。支持層(32)の厚み(D)に対する最表層(33)の厚み(C)の比(C/D)は、0.9以下である。
