摘要：
A filtration material including a silica base material having a group represented by the following general formula (a0-1) [in formula (a0-1), Ya01 represents a divalent linking group; Ra01 represents a hydrocarbon group which may have a substituent; Ra02 represents a hydroxyl group or a hydrocarbon group having 1 to 6 carbon atoms which may have a substituent; n01 represents an integer of 0 to 5; and the symbol “*” represents a valence bond with respect to the silica base material].
