We are developing the CALorimetric Electron Telescope, CALET, mission for the Japanese Experiment Module Exposed Facility, JEM-EF, of the International Space Station. Major scientific objectives are to search for nearby cosmic ray sources and dark matter by carrying out a precise measurement of the electrons in 1 GeV - 10 TeV and the γ rays in 20 MeV - several TeV. CALET has a unique capability to observe electrons and γ rays over 1 TeV since the hadron rejection power is more than 105 and the energy resolution better than a few % over 100 GeV. The detector consists of an imaging calorimeter by SciFi and W, and a total absorption calorimeter by BGO. CALET has also a capability to measure protons and nuclei up to 1000 TeV, and will have a function to monitor solar activity and γ ray bursts with additional instruments. The phase A study has started on a schedule of launch in 2013 by H-II Transfer Vehicle (HTV) for 5 years observation.
