We, JCEAM (Japan Consortium of Earth's Active Monitoring), are conducting research and development of an innovative resistivity structure electromagnetic exploration system at the Tokyo Tech seminar. Developed elements. At JCEAM, we theoretically elucidated the equivalent formulations of the electromagnetic vector A method and the electric field E method, and integrated them as the electromagnetic general-purpose AE hybrid method. We will point out the problems of the electromagnetic A-normal finite element currently used in 3D electromagnetic field analysis, and propose an electromagnetic general-purpose AE robust finite element to solve it.　　　　　　　　　　　　　　　　　　　　　　　Representative Fumio Kubo
