PSR B1259-63/SS2883 is a binary system which consists of a 48-ms radio pulsarand a massive star in a highly eccentric orbit with a period of about 3.4years. Non-pulsed and non-thermal emissions from this binary have been reportedin the radio, X-ray and TeV gamma-ray energy ranges. Light curves in the radioand X-ray bands showed characteristic double-peaked features which can beattibuted to the interactions of the pulsar wind and the Be disk during thecrossings by the pulsar. The TeV light curves around periastron differ between2004 and 2007 observations, and the feature is not conclusive. We report adetection of GeV gamma-ray emission around the periastron passage in December2010 with Fermi-LAT.
