The sealing tape for sealing a joint comprises two foam strips of flexible foam, which are not formed as integral parts of each other, and which are arranged next to each other in the functional direction of the sealing tape. A film strip is arranged between the foam strips and is bonded to both foam strips. Adhesion sites between the film strips and the first foam strip are arranged only in an upper area of the first foam strip and in a lower area of the first foam strip, whereas, in an intermediate area between the upper area and the lower area of the first foam strip, the film strip is not adhesively bonded to the first foam strip.
