We study the three-dimensional compact U(1) lattice gauge theory with N Higgs fields numerically. This model is relevant to multi-component superconductors, antiferromagnetic spin systems in easy plane, inflational cosmology, etc. For N=2, the system has a second-order phase transition line c1(c2) in the c2(gauge coupling)-c1(Higgs coupling) plane, which separates the confinement phase and the Higgs phase. For N=3, the critical line is separated into two parts; one for c2 \alt 2.25 with first-order transitions, and the other for c2 \agt 2.25 with second-order transitions.
