PROBLEM TO BE SOLVED: To provide a nonwoven cloth being easily deformed but hard to collapse and having excellent air permeability in the planar direction.SOLUTION: A nonwoven cloth comprises a continuous fiber and a bonded part formed by bonding a plurality of fibers including the continuous fiber. The nonwoven cloth comprises a first surface and a second surface which is the opposite side of the first surface the first surface comprises a plurality of projecting parts (V11) including the bonded part, a plurality of projecting parts (V12) not including the bonded part, and a recessed part (C11) the second surface comprises a plurality of recessed parts (C21) which is overlapped with at least some of the projecting parts (V11) including the bonded part on the first surface and the diameter variation coefficient of the continuous fiber is 10% or more.COPYRIGHT: (C)2015,JPO&INPIT【課題】変形しやすいが、潰れにくく、そして平面方向の通気性に優れる不織布を提供すること。【解決手段】連続繊維と、上記連続繊維を含む複数の繊維を接合することにより形成された接合部とを含む不織布であって、上記不織布が、第1の面と、第1の面と反対側の第2の面とを含み、第1の面が、複数の、接合部を含む凸部(V11)と、複数の、接合部を含まない凸部(V12)と、凹部(C11)とを含み、第2の面が、第1の面の、接合部を含む凸部(V11)の少なくとも一部と重なる、複数の凹部(C21)を含み、そして上記連続繊維の直径の変動係数が、10%以上であることを特徴とする不織布。【選択図】図1
