The CALorimetric Electron Telescope (CALET), operating onboard the International Space Station (ISS) since October 2015, is an experiment dedicated to high-energy astroparticle physics. The primary scientific goal of the CALET mission is to perform a high-precision measurement of the inclusive spectrum of cosmic electrons and positrons (all-electron) up to the multi-TeV region, where the shape of the spectrum can indicate the presence of nearby cosmic-ray sources or dark matter signatures. In this contribution, the analysis procedure that led to a precise measurement of the all-electron flux up to several TeV with the full statistics collected by the CALET experiment is presented and results are briefly discussed.

Abstract
The CALorimetric Electron Telescope (CALET), operating onboard the International Space Station (ISS) since October 2015, is an experiment dedicated to high-energy astroparticle physics. The primary scientific goal of the CALET mission is to perform a high-precision measurement of the inclusive spectrum of cosmic electrons and positrons (all-electron) up to the multi-TeV region, where the shape of the spectrum can indicate the presence of nearby cosmic-ray sources or dark matter signatures. In this contribution, the analysis procedure that led to a precise measurement of the all-electron flux up to several TeV with the full statistics collected by the CALET experiment is presented and results are briefly discussed.
