To reduce the amount of microorganisms floating in the air, by suppressing propagation of microorganisms collected by a filter medium for an air filter.SOLUTION: A filter medium for an air filter is a sheet-like filter medium for an air filter for collecting microorganisms in the air, which includes a collection layer comprising a fiber body having a plurality of fibers. The fiber has a contact angle with water of 75° or more. A filling rate of the collection layer is 9% or less. An average fiber diameter of the fibers is less than 0.5 μm.SELECTED DRAWING: Figure 1 【課題】エアフィルタ用濾材を用いて捕集した微生物の増殖を抑制し、空気中に浮遊する微生物の量を低減する。【解決手段】エアフィルタ用濾材は、空気中の微粒子を捕集するシート状のエアフィルタ用濾材である。複数の繊維を有する繊維体からなる捕集層を備える。前記繊維は、水との接触角が７５°以上である。前記捕集層の充填率は、９％以下である。前記繊維の平均繊維径は、０．５μｍ未満である。【選択図】図１
