The CALorimetric Electron Telescope(CALET) mission is proposed to measure galactic electrons and gamma
rays on ISS/JEM for three years[1]. In this paper we report the purpose of this project in solar physics and
the expected results from precise measurement of electron energy spectrum in the 1-100GeV energy range.
The CALET measurement of long-term variations of the energy spectrum will produce a wealth of data to
investigate electron propagation in the heliosphere. CALET does not distinguish positive charge from negative
one. However, we can evaluate the charge sign dependence of solar modulation using correlation with the
neutron monitors, since most particles are negative electrons in this energy range. Further we estimate transport
parameters, mainly the energy dependence of diffusion coefcient in the heliosphere. CALET will also have a
capability of measuring the short-term variation of around ten Forbush decreases(Fds) for three years. Precise
measurements of the energy spectral variation of Fds will give a conclusion of the energy dependence of Fds.
