Provided is a grip member having an electrothermal heater, wherein an end section of a metal strip does not curl up when the metal strip is attached. A metal strip (21) machined in strip-shape is embedded along a spiral flat groove section arranged on a core body (1) and fixed to the core body (1) at the both ends. An end portion (21a) of the metal strip (21) is inserted into a locking member (7), and the end portion (21a) is prevented from curling up. Since curl up of the end portion (21a) is suppressed, the metal strip is prevented from protruding to the outside from a synthetic rubber applied in the subsequent step and the thickness of the synthetic rubber at such section is prevented from thinning.
