One object is to provide a double bearing reel capable of visually and accurately determining a releasable state of an opening/closing mechanism for releasing a frame by cover plates, the opening/closing mechanism being prevented from causing tangling of a fishing line. The double bearing reel has an opening/closing mechanism for enabling a cover plate on an opposite side to a handle to be opened/closed with respect to a frame. Said opening/closing mechanism includes an operation member for switching between a releasable state where the frame is releasable by the cover plate and a closed locked state where the frame is closed by the cover plate and an indication portion for indicating the releasable state. In tandem with a switching operation, the indication portion is exposed outside of a side plate in the releasable state and retracted inside of the side plate in the closed locked state.
