An electrical reel is disclosed, which achieves miniaturization and lightweight characteristics and improves operability. The electrical reel (8) comprises a reel body (12), a spool (14), a motor (16), an operation part (18), a power receiving part (20), a rotation detection part (22), and a signal sending part (28). The reel body (12) includes a frame (34), a thumb seat (36), a first side cover and a second side cover. The frame (34) includes a first side plate (34a) and a second side plate. The thumb seat (36) is disposed at a position farther away from a rod-mounting seat (32) than an axis (X) of the spool (14). The first side cover (38) and the second side cover are used to respectively cover the first side plate (34a) and the second side plate. The operation part (18) is disposed for the operation of the motor (16). The power receiving part (20) receives the power from the outside to drive the motor (16). The rotation detection part (22) is used to detect the rotation of the spool (14). The signal sending part (28) is used to convert the information detected by the rotation detection part (22) into signals for wireless transmission outwardly.
