The purpose of the present disclosure is to provide a non-woven fabric for an outer covering sheet of an absorbent article, which is not prone to inducing a feeling of mustiness between an absorbent article and clothing on the part of a user. This non-woven fabric comprises the following configuration. In this non-woven fabric (13) for an outer covering sheet (6) of an absorbent article (1), said absorbent article comprising a liquid-impermeable sheet (5) which is moisture-permeable: the non-woven fabric (13) has a thickness direction (T), a planar direction (P), a first face (15), and a second face (17)； the non-woven fabric (13) includes thermoplastic resin fibers (19), and cellulosic fibers (21), at least a portion whereof configures a plurality of fiber masses (23)； the non-woven fabric (13) further comprises a plurality of spaces (27) which are adjacent to first regions (25) of each of the plurality of fiber masses (23), said first regions (25) facing the first face (15)； and each of the plurality of fiber masses (23) is not bonded to the thermoplastic resin fibers (19).本發明之目的係在於提供一種吸收性物品的外裝薄片用不織布，其藉由從不透液性薄片排出濕氣並且將濕氣封住於外裝薄片內，使得穿用者在吸收性物品與穿用著的衣服間之不會感到悶熱。本發明之不織布係具有以下的結構。一種吸收性物品的外裝薄片用不織布，係具備不透液性薄片(5)之吸收性物品(1)的外裝薄片(6)用不織布(16)，該不透液性薄片(5)具有透濕性，其特徵為：不織布(13)具有厚度方向(T)、平面方向(P)、第1面(15)以及第2面(17)，不織布(13)是包含有熱可塑性樹脂纖維(19)和纖維素系纖維(21)，該纖維素系纖維(21)之至少一部分構成複數個纖維塊(23)，不織布(13)具備有複數個空隙部(27)，這些複數個空隙部(27)是鄰接於複數個纖維塊(23)中各自的第1區域(25)，前述第1區域(25)是與第1面(15)相面對，複數個纖維塊(23)各自未與熱可塑性樹脂纖維(29)接合。
