The aesthetics of an elastic member including an elastic sheet is improved.In an elastic member, a first sheet layer 20A and a second sheet layer 20B are formed of a material having translucency, an elastic sheet 30 can be visually recognized through the first sheet layer 20A and the second sheet layer 20B, first non-joint bands 51 linearly continuous along a first direction 51d intersecting an stretchable direction ED at an acute angle are repeatedly present at intervals in a direction orthogonal to the first direction 51d as non-joint bands 51 and 52 in which a portion not having sheet joined portions 40 is continuous in an unfolded state in a stretchable region 80, a plurality of sheet joined portions 40 and joint holes 31 are provided at intervals between adjacent first non-joint bands 51 in the stretchable region 80, and a unit structure including a plurality of first non-joint bands 51 having different first widths 51w determined as widths in the direction orthogonal to the first direction 51d is repeatedly present in the direction orthogonal to the first direction 51d in the stretchable region 80.
