To provide a filtration object passability improving filter material which reduces passage resistance of a filtration object by randomly forming innumerable minute irregularities on a surface of a filter material, and a processing method for improvement in filtration object passability.SOLUTION: A filtration object passability improving filter material reduces a filter material resistance to improve passability of a filtration object by randomly forming innumerable minute irregularities on at least a part of a surface contacting the filtration object. Further, a processing method for improvement in filtration object passability reduces a filter material resistance to improve passability of a filtration object by performing processing for randomly forming innumerable minute irregularities on at least a part of a surface contacting the filtration object.SELECTED DRAWING: Figure 14 【課題】 濾材の表面に微小凹凸を無数にランダムに形成することで、濾過対象の通過抵抗を低減した濾過対象通過性向上濾材及び濾過対象通過性向上処理方法を提供する。【解決手段】 本発明に係る濾過対象通過性向上濾材は、濾過対象と接触する表面の少なくとも一部に微小凹凸を無数にランダムに形成したことで、濾材抵抗を低減して濾過対象の通過性を向上させたことを特徴とする。また、本発明に係る濾過対象通過性向上処理方法は、濾過対象と接触する表面の少なくとも一部に微小凹凸を無数にランダムに形成する処理を施すことで、濾材抵抗を低減して濾過対象の通過性を向上させることを特徴とする。【選択図】図１４
