To provide a corner bead which is available for a baseboard, a ceiling cornice, and a border cloth, can be easily and positively mounted, and can be easily exchanged for another one.

A corner bead main body (20) of the corner bead is formed of a band-shaped soft synthetic resin sheet or cloth having a predetermined thickness, and therefore it can be wound in and off. A rear surface of the main body has a tackiness agent (22) applied thereto, which has a release sheet (23) releasably stuck thereto. Pressing beads (21) for pressing both edges of the corner bead main body in a width direction are formed of the soft synthetic resin or cloth, and they each have a width which is sufficient enough for pressing both the edges of the corner bead main body in the width direction and do not hinder the corner bead main body from being wound in and off. The pressing beads are molded in one body with the main body over the entire length thereof in a longitudinal direction.
