The CALorimetric Electron Telescope, CALET, mission is proposed for the Japanese Experiment Module Exposed Facility, JEM-EF, of the International Space Station. The mission goal is to reveal the high-energy phenomena in the universe by carrying out a precise mesurement of the electrons in 1 GeV - 10 TeV and the gamma-rays in 20 MeV - several TeV. The instrument will be composed of an imaging calorimeter of scintillating fibers and a total absorption calorimeter of BGO. The total thickness of absorber is 36 r.l for electro-magnetic particles and 1.8 m.f.p for protons. Total weight of the payload is nearly 2,500 kg, and the effective geometrical factor for the electrons might be ∼1.0 m2sr. The CALET has a unique capability to measure the electrons and gamma-rays over 1 TeV since the hadron rejection power can be 10 6 and the energy resolution of electro-magnetic particles is better than a few % over 100 GeV. Therefore, it is promissing to detect the change of energy spectra and the line feature of energy distribution expected from the dark matter. We are expecting to launch the CALET around 2010 by the Japanese H-II Transfer Vehicle, HTV, and to carry out the observation more than three years.
