An electrode device for microwave coagulation therapy in which the direction of its electrode tip carried on a support shaft can be controlled by operation in i ts proximal region. A distal part of a support shaft of the electrode is separated into one or more links whose angles can be altered in a single plane, and arranged so that th e most distal one of the links can be pulled and pushed back on its deflection side from a proximal region by means of an elongated resilient member along the inner surface of the support shaft. Thus, the direction of the distal end of the electrode containing a coaxial cable can be easily and reliably controlled from the proximal region of the electrode.
