The Solar Mean Magnetic Field (SMMF) is generally defined as disc-averaged line-of-sight (LOS) magnetic field on the sun. The role of active regions and the large-scale magnetic field structures (also called the background) has been debated over past few decades to understand whether the origin of SMMF is either due to the active regions or the background. In this paper, we have investigated the contribution of sunspots, plages, network regions and the background towards the SMMF using data from the SDO-AIA \& HMI, and found that 83\% of the SMMF is due to the background whereas the remaining 17\% originates from the active and network regions.
