We carried out search of globular clusters (GCs) in M82 by taking advantage of high-resolution imaging and deep spectroscopic capabilities provided by FOCAS on the Subaru telescope. Recently a number of possible young GCs have been found in some merging/interacting galaxies or starburst galaxies. On the other hand it is well known that GCs are numerous in giant elliptical galaxies many of which are thought to be formed via major merger of galaxies. These facts lead us to a thought that the formation process of GCs could accompany galaxy -- galaxy interaction followed by starburst. The archetypical starburst galaxy M82 is an ideal target to study the relation between galaxy interaction starbust and GC formation. In the central 6 arc-minutes diameter region of M82 we found two bona fide GCs and 8 young GC candidates in our first attempt at searching for GCs in M82. The estimated total number of bona fide GCs is about 10 corresponding to the expected number from the initial luminosity of M82. We conclude that M82 has a GC system with our Galactic specific frequency before the interaction and newly born GCs should be formed by the tidal interaction with M81.
