The invention relates to a middle-through electrical fishing line wheel which comprises a shell, a line discharger, an electric motor and a reel. In a cavity inside the shell, the line discharger, the electric motor and the reel are sequentially arranged from front to back. A line discharger gear and an electric motor rotation gear which are connected mutually are respectively arranged at the left ends of the line discharger and the electric motor. A rocker switch is arranged between the reel and the line discharger, the rocker switch is matched with an electromagnetic sucker, and the phenomenon of line tying on the reel can be prevented. The middle-through electrical fishing line wheel has the beneficial effects that the middle-through electrical fishing line wheel has double manual and electrical functions, adopts a middle-through line outlet mode, can achieve a remote line throwing function, and is convenient to operate; a line paying-off speed is automatically controlled; the phenomenon of line tying of a fishing line on the reel can be prevented.
