Abstract
At least two layers are fixed together at a distance so that a gap is present between them, wherein the layers are connected with one another by a plurality of discrete melt adhesive regions, intermediate spaces being present between the melt adhesive regions so that a liquid transport in the gap between the layers is assured through the intermediate spaces. To produce this test carrier, the melt adhesive in the form of discrete regions, between which intermediate spaces are present, is applied to a first layer material in a thickness which is greater than the desired gap and a second layer material is pressed against the melt adhesive regions while the melt adhesive is still sufficiently hot in order to be bindable in such a manner that it binds with the melt adhesive but a gap remains between the layer materials.
