PROBLEM TO BE SOLVED: To provide a fluid filter capable of collecting and removing every particle ranging from fine particles to relatively coarse particles with its high collection performance while suppressing increases in pressure loss. SOLUTION: The fluid filter 1 is made of a filter having a three-dimensional reticular skeletal structure and is provided with a convexo-concave-shaped part 1C on at least a part of the surface. The filter surface area is increased by forming the convexo-concave-shaped part on the filter surface with the three-dimensional reticular skeletal structure, whereby the fluid filter having good refuse-collecting performance while suppressing initial increases in pressure loss and increases in the same after passage of time can be obtained.
