The present invention provides a safe, efficient, nonpolluting and economical method for inactivating viruses in a biomaterial, characterized in comprising a step of introducing a high-pressure fluid into a container containing a biomaterial to be treated at a speed capable of forming non-turbulent flow with Reynold's number of 2000 or less, thereby inactivating viruses potentially existing in the biomaterial. The method in accordance with the present invention can inactivate or eliminate viruses in a heat-sensitive biomaterial such as proteinous material, without decreasing the biological activities of the biomaterial significantly.
