An object of the disclosure is to provide a nonwoven fabric that is easily deformed but resistant to collapse, and that has excellent air permeability in the planar direction. The nonwoven fabric of the disclosure is as follows. A nonwoven fabric comprising continuous fibers and bonded sections formed by bonding multiple fibers including the continuous fibers, wherein the nonwoven fabric comprises a first side and a second side on the side opposite the first side, the first side comprises a plurality of projections (V11), each projection (V11) including at least one bonded section, a plurality of projections (V12) including no bonded section, and at least one recess (C11), the second side comprises a plurality of recesses (C21), each recess (C21) overlapping with at least a part of the projection (V11) of the first side, and the coefficient of variation of the diameters of the continuous fibers is at least 10%.
