Provided is an adhesive label that does not use release paper, is excellent in environmental resistance from the viewpoint of saving resources, is capable of controlling the position and area of an adhesive layer to be exposed with high precision so that adhesive strength is adjustable with ease depending upon the properties of an adherend. An adhesive label includes a support, an adhesive layer placed on the support, and a non-adhesive porous layer placed on the adhesive layer. The porous layer has a heat capacity smaller than that of the same material that is not porous, and hence, is opened with low heat energy, which is preferred for a portable label issuing device.
