The invention addresses the problem of providing a filter medium for a liquid filter, which has a low weight per unit and yet has high strength, high collectability, and a long life, and also a liquid filter. As a means for resolution, using a main fiber having a fiber diameter of 4.0 µm or less and an aspect ratio of 100 to 2,500 and a binder fiber having a fiber diameter of 3.0 µm or less and an aspect ratio of 100 to 2,500, a filter medium for a liquid filter in which the weight proportion of the binder fiber relative to the weight of the filter medium is 10 to 50 wt%, and the weight per unit is within a range of 5 to 80 g/m 2 , and also a liquid filter are obtained.
