It is based on the dual nature of matter.
The wavelength of waves corresponding to a particle are given by formula: λ=h/p, where h=Planck's constant and p= momentum of particle.
The waves corresponding to electrons are much smaller than electromagnetic waves, so using electrons allows us to see even smaller structures like individual atoms.
Quote from Wikipedia: "As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects."

Electrons are used in electron microscope due to their small wavelength,
and high resolving power of the microscope due to the use of them..
