We have developed a planar transition radiation detector to be used for electron tagging in the experiment of heavy quark decay. It consists of a radiator of multilayer polypropylene foils and a Xe gas multiwire proportional chamber for X-ray detection. The performance was tested in the mixed $\pi/e$ beam of several GeV/c range. With four modules of this type, the pion contamination less than 3.5% was achieved at the electron detection efficiency of 90% over the effective area of $55\times 55$ cm2. Some important feature for the stable operation are also discussed.
