An electrically heated handle, particularly for fishing rods, has an elongated thermally conductive shell enclosing an interior chamber in which is located a solid body of a material having high electrical resistance, such as Steatite, defining a heater core having its entire outer surface in heat transfer engagement with the shell. An elongated electric heating coil, e.g., of Nichrome, extends longitudinally through the interior of the heater core and is connected to an external power source through a switch and power supply conductors extending through the rear end portion of the handle. The front end portion of the handle is formed with an elongated socket chamber thermally insulated from the interior chamber and adapted to receive and fit over the butt end of a fishing rod. Once the heater core of the handle is initially heated, the heat is stored for slow dissipation to the handle and hand of the holder, requiring infrequent replenishing of electric current to the electric heating coil. The electrically heated handle may be modified for connection to the handle of a electric trolling motor. The switch may be mounted in the handle or formed as a separate external unit detachably connected to the handle by a separable connector plug, and may be a manual off-on switch, timer or thermostat.
