Abstract
A filter that contains carbonized cellulose fibers obtained by carbonizing cellulose fibers and capture a specific substance is provided. The carbonized cellulose fibers have a large number of pores opening to the surface, and the number of the pores having a pore diameter of 4.0 nm or more and 60 nm or less is larger than the number of the pores having a pore diameter of 0.8 nm or more and 1.2 nm or less. In the frequency distribution of the pore diameters, when the frequency of the pores having a pore diameter of 4.0 nm or more and 60 nm or less is A and the frequency of the pores having a pore diameter of 0.8 nm or more and 1.2 nm or less is B, A/B is preferably 1.5 or more and 100 or less.
