Summary

The electronic state of an MgB2 superconductor is reviewed, focusing on its characteristics properties such as the multi-bands and multi-gaps. The presence of two superconducting gaps causes the temperature dependence of the anisotropy in the upper critical fields. The carbon impurities can be substituted for B and act as strong scattering centers, particularly for the sigma-band carriers. The s-wave symmetry of the gaps is an advantage to achieve a higher critical current.
