Zusammenfassung:	To provide a melt-blown non-woven fabric in which an increase in pressure loss is suppressed even though a tannic acid layer exists on the surface layer of the melt-blown non-woven fabric as a collection filter medium.MEANS FOR SOLVING THE PROBLEM: Provided is a melt-blown non-woven fabric, which is a melt-blown nonwoven fabric that has a tannic acid-containing tannic acid layer on the surface layer, and in which, characterized, the contained amount of tannic acid is 0.1 g/m2 or more and 3.0 g/m2 or less, and the tannic acid layer contains a surfactant.SELECTED DRAWING: None 【課題】本発明が解決しようとする課題は、捕集濾材であるメルトブロー不織布の表層にタンニン酸層が存在していながらも、圧力損失の上昇が抑えられたメルトブロー不織布を提供することである。【解決する手段】表層にタンニン酸を含有するタンニン酸層を有するメルトブロー不織布において、該タンニン酸の含有量が０．１ｇ／ｍ２以上３．０ｇ／ｍ２以下であり、該タンニン酸層が界面活性剤を含有することを特徴とするメルトブロー不織布。【選択図】なし
