<p>PROBLEM TO BE SOLVED: To provide a ventilation member which is suitable for maintaining a filter function even when a foreign object adheres thereto or large impact is applied thereto.SOLUTION: A ventilation member 1A includes: a first porous body 2 which ventilates in a direction perpendicular to a main surface; and a second porous body 3 which is provided so as to overlap with the first porous body 2 when viewed from the direction perpendicular to the main surface. The second porous body 3 is integrally provided with the first porous body 2 at a position such that a space 5 is secured between the first porous body 2 and the second porous body 3. The second porous body 3 is formed by a porous resin and ventilates in the direction perpendicular to the main surface. The first porous body 2 is formed by the same porous resin as the porous resin forming the second porous body 3. The first porous body 2 and the second porous body 3 are plate-like rigid bodies. The first porous body 2 and the second porous body 3 are integrally molded by injection molding.</p> |
