概要	CALET (CALorimetric Electron Telescope) is a high energy cosmic-ray detector to be installed on International Space Station in 2015 to carry out accurate measurements of high energy electrons and gamma-rays. For verification of the detector performance, we carried out balloon experiments using CALET prototype detectors in May 2006 (bCALET-1) and in August 2009 (bCALET-2). In this paper we mainly report about the second experiment using bCALET-2. bCALET-2 is a calorimetric instrument composed of a 3.58 radiation length thick tungsten-scintillating fiber imaging calorimeter (IMC) and a 13.4 radiation length thick bismuth-germanium-oxide calorimeter (TASC). The concept of the structure is similar to that of CALET, but the number of sensors and the thickness of materials were optimized for the balloon experiment.
