Air bubbles are removable with the use of an air vent structure having a compact and simple configuration. An air vent hole is formed in an upper plate that covers an entire upper end surface of a filtration section having a substantially tubular shape formed by bending a thin plate in a pleat shape. A moving member is provided to be movable between a position of closing the air vent hole and a position of opening the air vent hole.
