The recent collaboration between theory and experiment has led to the discovery of high-Tc superconductive hydrogen dominant compounds under ultra-high pressure over one million atmospheres which can be attained by the recent advances in technology using diamond anvil cell. Although there are still various difficulties in measuring the physical properties of materials under ultra-high pressure, high-pressure is expected as an important parameter for development of novel functional materials and search for physical properties, which cannot be realized at ambient pressure. In this article, I review the recent results on the search for pressure-induced superconductivity in sulfur hydride system.
