Particle physics allows us to know which the constituent of matter and their interaction are. According to Standard Model with success, three of the four fundamental interactions, the strong interaction, the weak interaction and electromagnetic interaction. Fundamental particle is a sub-atomic particle with no sub-structures. Thus not composed of other particles. In the physical sciences, sub-atomic particles are particle much smaller than atom. We review the status of electron as a fundamental particle. We also highlight the essentials of Dirac Equation for electron, Quantum Electrodynamics and present day elementary particle physics where electron as fundamental particle plays a major role. Recent ideas on preon model, string theory as well as leptoquarks questioning the fundamental nature of electron are also discussed.
