 note = {We present preliminary results on the spectrum of high energy
cosmic-ray electrons as the measured in the flight
of the Polar Patrol Balloon (PPB) which lasted for 13 days,
in January,2004 with a launch from Syowa Station, Antarctica.
The PPB-BETS (Balloon-borne Electron Telescope with Scintillating
Fiber) detector is designed to measure the cosmic-ray electron spectrum
from 10 GeV to 1 TeV during a long balloon flight.
It consists of 9 plates of plastic scinlater as a calorimeter
and a scintillating fiber trackers for cascade showers
induced from high energy electrons and protons
between plates of lead with total 9 radiation length thickness.
In this paper, we discuss the perfomance of the detector
and the preliminary results on the spectrum of cosmic-ray electrons., 35th COSPAR SCIENTIFIC ASSEMBLY},
