摘要： PROBLEM TO BE SOLVED: To improve trapping performance and discharging performance of moisture dispersing in fuel.SOLUTION: A fuel filter apparatus 10 includes a moisture collector 50. The moisture collector 50 includes a fiber assembly 51. When the fuel passes the fiber assembly 51, moisture is trapped with fibers and agglomerated to form droplets which precipitate in a container 20. A lower plate 55 of a support member 52 has a slope. The droplets trapped on the fiber assembly 51 are guided through the slope to an outlet. Furthermore, the slope compresses the fiber assembly 51, and distribution of fiber density in which a high density part is positioned on an inlet side, and a low density part is positioned on an outlet side is given. As a result, gaps of the fibers are enlarged as the droplets grow along a flow direction of the fuel. As a result, trapping and agglomeration of moisture can be facilitated, and separation from the fiber assembly 51 can be facilitated.
