A wound dressing comprises a first layer 10 including a sheet that exerts a water pressure resistant function at an initial stage, a second layer 20 including an absorptive material, and a third layer 30 including a sheet impermeable to liquid. The first layer 10, the second layer 20 and the third layer 30 are integrally stacked together so that the second layer 20 is sandwiched between the first layer 10 and the third layer 30. The wound dressing will not be completely stuck on the wound surface, the exudates can be adequately held on the wound surface, and the exudates can be prevented from leaking to the outside through the dressing.
