PROBLEM TO BE SOLVED: To provide a high discreteness liquid filter with high collectability and collection precision of submicron particles in liquid. SOLUTION: The liquid filter is a filter for filtering solid matter in liquid. A main filtering material, containing nonwoven fabric, which is 0.2-1.0μm in an average fiber diameter, 50-300 g/m<SP>2</SP>in an basis weight, 45-75% in porosity, 0.3-2.0μm in average flow rate pore diameter and has variations in opening diameter of not more than 200%, is formed into a pleat shape.
