The Calorimetric Electron Telescope (CALET) is a new space experiment for astroparticle physics, which will carry out a five-year observation at the Japanese Experiment Module-Exposed Facility (JEM-EF) of the International Space Station (ISS). The experiment, currently under development by Japan in collaboration with Italy and the United States, will measure mainly the flux of cosmic-ray electrons (including positrons) to 20 TeV, gamma-rays to 10 TeV, and nuclei with Z=1 to 40 up to 1000 TeV. We have carried out a beam test of the CALET calorimeter at CERN-SPS by using the Beam-Test Model (BTM), which consisted of the Structure and Thermal Model (STM) and the Bread Board Model(BBM) of the front end circuits. The model consists of the same support structure as the CALET flight model and it includes the Imaging Calorimeter (IMC), the Total Absorption Calorimeter(TASC) and the Charge Detector(CHD). A part of the sensors; the scintillating fibers in the IMC, the PWO logs in the TASC, and the plastic scintillators paddles in the CHD, was adapted for the test. We will describe the model, and will report the basic performance obtained in the beam test.
