摘要： A reactor includes a core body having an outer peripheral iron core, at least three iron cores contacting or coupled to an internal surface of the outer peripheral iron core, and coils wound on the iron cores. The reactor has a terminal base including terminals connected to the coils and connected to cables through current-carrying portions, and an electrical shock protection cover for covering the terminal base. The electrical shock protection cover includes a main portion for covering the current-carrying portions, and cable covering portions extending from the main portion to cable drawing directions so as to cover a part of each cable. The terminal base includes a main portion for supporting the current-carrying portions, and cable receiving portions in which passages are formed to pass the cables therethrough between the cable receiving portion and the cable covering portion.
