A case body of a fan case in a jet engine is formed by use of a composite material of carbon fiber reinforced plastic. Metal rings are respectively attached to a leading edge and a trailing edge of the case body. The metal rings are electrically connected together by a conductive cable. Both of the metal rings and the conductive cable constitute a path of a lightning current.
