In the electric fishing reel, even if the adjustment stages of the adjusting member is increased, it is still possible to suppress the volume increase of the installation portion of the adjusting member at a low cost. The electric fishing reel (100) includes a reel main body (1), a coil (10), a motor, an adjusting member (5), a first magnet (34a) and a second magnet (34b), and a phase detecting part (35). The coil (10) is rotatably disposed on the reel main body (1). The motor is disposed within the reel main body (1), and drives the coil (10) to rotate. The adjusting member (5) is rotatably mounted on the reel main body (1) and is used to adjust the output of the motor (12) according to the rotational position. The first magnet (34a) and the second magnet (34b) are provided on one of the reel main body (1) or the adjusting member (5), and the phase detecting unit (35) is provided on the other one of the reel main body (1) and adjusting member (5) and is capable of detecting the relative rotational phase of the first magnet (34a) and the second magnet (34b).在電動捲線器中，即使調整構件調整之級層增多，仍可以低成本抑制調整構件之安裝部分之體積之增加。電動捲線器100具備捲線器本體1、線圈10、馬達、調整構件5、第1磁鐵34a及第2磁鐵34b、及相位檢測部35。線圈10可旋轉地設置於捲線器本體1。馬達設置於捲線器本體1，且旋轉驅動線圈10。調整構件5可轉動地設置於捲線器本體1，且為用以根據轉動位置調整馬達12之輸出之構件。第1磁鐵34a及第2磁鐵34b設置於捲線器本體1及調整構件5之一者。相位檢測部35設置於捲線器本體1及調整構件5之另一者，可檢測與第1磁鐵34a及第2磁鐵34b之相對之旋轉相位。
