As a wound dressing that includes a perforated material having through-holes, in which the perforated material can be coated with a low-adhesive resin without closing the through-holes, and that has excellent adhesion prevention properties to wounds, provided is a wound dressing 1 that includes a sheet-shaped perforated material 11 having through-holes 111 and a low-adhesive resin 12 with which at least one face of the perforated material 11 is coated without closing the through-holes 111, the perforated material 11 is a knitted fabric or a woven fabric formed of a multifilament, and the perforated material 11 has an average opening area of the through-holes 111 of 0.02 to 1.2 mm 2 and an average number of through-holes of 40 to 220 cm -2 . By designing the opening area of the through-hole 111 and the number of through-holes 111 in the perforated material 11 within the particular numerical ranges, such a wound dressing can be prevented from adhering to granulation tissues that invade the through-holes 111 and can ensure sufficient permeation properties of exudate through the through-holes 111. |
