Provided is a filter comprising: a capsule (CA) that has a side wall (10) that constitutes the side surface of a tube shape and a pair of end walls (11, 12) that close each of the front and rear openings of the tube shape, that has a liquid encapsulated therewithin, and in which at least the side wall (10) is elastically deformable and at least one circular main thin-walled area (10a) is provided along the peripheral direction of the side wall or at least one linear main thin-walled area (10c) is provided along an axial direction that is perpendicular to the peripheral direction; and an approximately cylindrical filter main body that is formed so as to include an accommodation space (204) that accommodates the capsule (CA). A direction in which either the circular main thin-walled area (10a) or the linear main thin-walled area (10c) extends and the radial direction of the filter main body are configured so as to be parallel, and the capsule is accommodated within the accommodation space. |
