SU(2)+Higgs model, which describes several important phenomena of particle physics and condensed matter physics, has been investigated using Monte-Carlo simulation for many years. In this talk, we discuss phase structure of SU(2)+multiple Higgs model. Especially we show exploratory results for zero-temperature phase structure.
