PROBLEM TO BE SOLVED: To extend the life of a filter by suppressing deterioration of filtration performance. SOLUTION: A filter medium 10 includes a support layer 1 and a filtration layer 2 in which one surface is laminated so as to be fixed to the support layer 1 and the other surface is a filtration surface on which a filtration object is deposited. The filter medium 10 contains lyocell fibers and synthetic fibers having a fiber length of 1 mm to 3 mm. With the above configuration, the surface of the filter medium 10 is smoothed so that particles can easily fall from the surface of the filter medium 10 due to its own weight when the filter medium 10 is in a vertical posture or an oblique posture. The decrease can be suppressed. [Selection diagram] Fig. 1
