  In the present study, we identified an extremely low-mass white dwarf as a
companion to a low luminous blue straggler star within the Galactic globular
cluster NGC 362. To conduct the analysis, we utilized data obtained from
various sources, including AstroSat Ultra Violet Imaging Telescope, UVOT, and
the 2.2-m ESO telescope. By examining the spectral energy distribution of the
blue straggler star candidate, we successfully identified an extremely low mass
white dwarf as its binary companion. We determined the effective temperature,
radius, and luminosity for both, the extremely low-mass white dwarf and the
blue straggler star candidate. Specifically, the extremely low-mass white dwarf
exhibits an effective temperature of 15000 K, a radius of 0.17 Rsun, a
luminosity of 1.40 Lsun, and a mass range of 0.19-0.20 Msun. Furthermore, the
position of the straggler star within the cluster suggests their formation via
the Case A/B mass-transfer mechanism in a low-density environment.
