Cosmic-Ray Electrons (CREs) lose energy rapidly during their propagation and constraint themselves in local galactic space. Hence, a detailed measurement of the spectra extending to tens of TeV is a probe to CRE origin, from sources or from more exotic production mechanisms. Ground-based imaging atmospheric Cherenkov telescopes have measured CREs up to 10 TeV. However, measurements of CREs spectrum above 10 TeV with ground-based arrays are still challenging due to the difficulty in rejection of hadronic background. The LHAASO with a large effective area and strong background rejection power is very suitable for investigating the CREs. Combining KM2A and WCDA, we can get a more efficient rejection of the hadronic background. In this proceeding, we'll discuss the status of the CRE spectrum measured with LHAASO.
