PROBLEM TO BE SOLVED: To provide an electric reel for fishing, with which a fishing rod and a reel body can be easily held by one hand, as well as an operation member for adjusting the output of a motor can be skillfully operated by the thumb of the hand, and in addition, which has sufficient holdability during operating the operation member and even when a big load is applied thereto.SOLUTION: An electric reel for fishing includes a spool around which a fishline is wound, a drive motor installed to a reel body 5 and rotatively driving the spool, an operation member 30 for adjusting the output of the drive motor, and a control case 15 in which a control unit for controlling the drive motor is housed. The operation member 30 is placed in the control case in a state of being exposed from a surrounding surface in the rear side of the control case 15 and on the upper part of at least one of left and right side plates, as well as mounted to a spindle 31 supported to be almost parallel to the spool shaft of the spool, and an angle sensor 130 for detecting the operation angle of the operation member 30 is installed in the control case.COPYRIGHT: (C)2014,JPO&INPIT【課題】釣竿とリール本体を片手で容易に把持できるとともに、その手の親指でモータ出力を調整する操作部材を巧みに操作でき、更には、操作部材の操作中や急に大きな負荷がかかっても十分な把持性を有する魚釣用電動リールを提供する。【解決手段】本発明に係る魚釣用電動リールは、釣糸が巻回されるスプールと、リール本体5に設けられ、スプールを回転駆動する駆動モータと、駆動モータの出力を調整する操作部材30と、駆動モータを制御する制御部を収容した制御ケース15とを有する。操作部材30は、制御ケース15の後方側で少なくとも左右の側板の一方の上部に周辺の表面から露出した状態で制御ケースに配設されるとともに、スプールのスプール軸と略平行に支持された支軸31に略前後方向に回転可能に装着されており、制御ケースには、操作部材30の操作角度を検知する角度センサ130が設けられている。【選択図】 図1
