Abstract
Provided are a fastening member and a fastening piece for which an unpleasant texture and an incongruous appearance are significantly reduced, and that bring about an integrated feeling with the main body of a disposable article for wearing. A fastening segment includes a hook fastener and a base sheet. A hook height H1 of a hook is set to 45 μm to 150 μm, and a hook sheet thickness T2 is set to 45 μm to 75 μm. When in an L*a*b* color coordinate system, a color difference of L* is ΔL*, a color difference of a* is Δa*, and a color difference of b* is Δb*, a color difference ΔE between the hook fastener and the base sheet calculated using the ΔL*, the Δa* and the Δb*, is less than 5.5.
