Abstract

In an elastic member, a first sheet layer and a second sheet layer are formed of a material having translucency. An elastic sheet can be visually recognized through the first sheet layer and the second sheet layer. First non-joint bands linearly continuous along a first direction intersecting an stretchable direction at an acute angle are repeatedly present at intervals in a direction orthogonal to the first direction as non-joint bands in which a portion not having sheet joined portions is continuous in an unfolded state in a stretchable region. Sheet joined portions and joint holes are provided at intervals between adjacent first non-joint bands in the stretchable region. A unit structure including a plurality of first non-joint bands having different first widths determined as widths in the direction orthogonal to the first direction is repeatedly present in the direction orthogonal to the first direction in the stretchable region.
