Abstract
Abstract A multielectrode probe of this invention is inserted into a patient when in use. This probe includes a base on which a plurality of signal lines are bonded. Each of the plurality of signal lines has at least one electrode, and these electrodes are arranged on the base with predetermined spacings between them. The electrodes are formed by stripping the isolating coatings of the plurality of signal lines.
