A trigger structure for use in a fishing rod comprises: a mounting portion mounted on a grip portion of the fishing rod; and a trigger portion which perpendicularly projects from the above mounting portion so as to be bendable when such trigger portion is subjected to an outer forcible force. The trigger portion of the trigger structure is an injection molding product made of plastic so as to give an excellent touch feeling, whereby there is no fear that such trigger portion does some damages to the user's finger and hand even when such trigger portion hits the user in his finger and hand strongly at time when he performs his rapid hand changing operation in the fishing rod.
