A photonic crystal that can spatially control the resonance efficiency and reduce the leakage of light in transversal directions and a surface emitting laser that can be formed by using such a photonic crystal are provided. The photonic crystal has a first region and a second region having a same periodic structure as fundamental structures thereof and defects are introduced into the periodic structure of the first region, which is arranged around the second region.
