Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water removing filter optimum for removing water (soil water) adhering to or contained in the soil, by paying attention to material or characteristic of a filter targeting the soil which has been hardly examined hitherto.SOLUTION: In a water removing filter 20 for removing water adhering to or contained in the soil which is constituted of a hydrophilic polymer material, an air intrusion pressure which is a pressure at which the air intrudes into the suction side when sucking in the atmosphere in the water-saturated state is set at 1 KPa or higher. 【課題】これまであまり検討されていなかった土壌を対象としたフィルターの材質及び特性に着目し、土壌に付着する又は含有される水（土壌水）の除去に最適な水除去用フィルターを提供する。【解決手段】土壌に付着する又は含有される水を除去する水除去用フィルター２０であって、親水性高分子材料から構成され、飽和含水状態にして大気中で吸引を行ったとき、吸引側に空気が侵入する圧力である空気侵入圧力が１ＫＰａ以上に設定されている。【選択図】図２
