First results of a cosmic-ray electron + positron spectrum, from 10 GeV to 3TeV, is presented based upon observations with the CALET instrument on the ISSstarting in October, 2015. Nearly a half million electron + positron events areincluded in the analysis. CALET is an all-calorimetric instrument with totalvertical thickness of 30 $X_0$ and a fine imaging capability designed toachieve a large proton rejection and excellent energy resolution well into theTeV energy region. The observed energy spectrum over 30 GeV can be fit with asingle power law with a spectral index of -3.152 $\pm$ 0.016 (stat.+ syst.).Possible structure observed above 100 GeV requires further investigation withincreased statistics and refined data analysis.
