Summary:Magnetic reconnection is one of the important physical mechanisms for the conversion of magnetic energy into plasma energy, which is closely related to many explosive phenomena in space. Magnetic reconnection is a cross-scale physical process, in which the physical process at the electron-scale plays key roles in triggering reconnection and facilitating reconnection fast, hence it has attracted much attention. After the launch of the magnetospheric multiscale (MMS) satellite in 2015, the unprecedented high-resolution data provided by MMS enable us to have a new understanding of the electron-scale physics. This paper briefly summarizes the recent research progresses of electron-scale physics in magnetic reconnection based on the observational results of MMS. We divided the reconnection region into the electron diffusion region, ion diffusion region and reconnection exhaust, and summarized the electron scale physical processes from many aspects. The main contents are as follows: The electron diffusion region ca
