We describe a scintillating-fiber telescope which is to be operated on board a satellite for the observation of gamma rays from 20 MeV to a few hundred GeV. The telescope consists of a track detector composed of scintillating-fiber belts and lead plates, and a total absorption spectrometer crystal (TASC). The merit of using scintillating fibers is that the area of telescope can be enlarged more than one meter square without any particular technical difficulty. The basic performance of the telescope is shown by using simulation calculations and accelerator tests. Results of balloon experiments for primary cosmic electrons are also presented to show the tracking capability of scintillating fibers. Key words: gamma-rays: observations -instrumentation: detectors -telescopes.
