A fluid filtering member is provided with three layers including a dense layer having first and second surfaces and performing a filtering function, and a pair of rough layers respectively connected to both surfaces of the dense layer and functioning as a passage. A V-shaped member is formed by connecting edge portions of two sheets of materials to one another. The V-shaped member may be formed either by folding a single sheet of material in a longitudinal direction or by connecting edge portions of two lapped sheets of materials in a longitudinal direction. When the V-shaped bodies are rolled, the rough layer at an opening edge of one V-shaped member is connected to the rough layer at an opening edge of an adjacent V-shaped member by heat-welding to form the fluid filtering member. The fluid filtering member can simplify the manufacturing process and can decrease the manufacturing cost. Further, the fluid filtering member can improve durability and reliability the fluid filtering member.
