To provide an electromagnetic wave radiation detection member, an electromagnetic wave radiation detection method, and a device including the electromagnetic wave radiation detection member that make it possible to determine whether an object to be detected has been heated by electromagnetic wave radiation by a microwave oven or the like. In the optical integrated circuit substrate, on a substrate is formed an optical waveguide having a clad and a core layer. A response is generated based on the concepts in the database and their relationship to the concepts in the input array.
