N2 - The CALET (CALorimetric Electron Telescope) instrument is proposed for the observation of TeV electrons at the Japanese Experiment Module Exposure Facility (JEM/EF) on the ISS, which is composed of an imaging calorimeter with scintillating fibers and lead plates, and a total absorption calorimeter with BGO logs. Since TeV electrons could reach only from the nearby sources within a distance less than 1 kpc, we can expect that the energy spectrum has a structural component and the arrival directions show an anisotropy. Therefore, we should be able to localize and identify the nearby cosmic-ray sources by the TeV electron observation. We report the status of development of the CALET instrument, which has a capability to observe electrons up to 10 TeV and a proton rejection power of ~ 106. We expect to observe ~ 103 events over 1 TeV during the 3 years observation. By using the excellent imaging capability of the CALET, gamma-rays over the GeV region and the nuclear components up to 1015 eV might also be observed.
