We review the construction of the N=2 U(N) gauge model and the analysis ofvacua of the model. On the vacua, N=2 supersymmetry is spontaneously broken toN=1, and the gauge symmetry is broken to a product gauge group \prod_{i=1}^nU(N_i). The masses of the supermultiplets appearing on the N=1 vacua are given.We provide a manifestly N=2 supersymmetric formulation of the U(N) gauge modelcoupled with N=2 hypermultiplets, and show that N=2 supersymmetry is partiallybroken down to N=1 spontaneously.Comment: 13 pages 1 figure, PTPTeX.cls, Talks given at ``Frontier of Quantum Physics''(YITP Kyoto Univ., Feb. 2005) and at ``Progress of Quantum Field Theory and String Theory'' (OCAMI, Feb. 2006
