摘要

The present invention relates to an edge insulation member for an electrode plate used for electrolytic refinement of metal, and to a fixing method for it. On a tip portion 22A of a main body 22, a fitting groove 23 and a jaw portion 24 for tightly fitting an electrode plate 1 are formed to extend along the lengthwise direction of the main body 22. On a base end portion of the main body 22, an engagement notch 25 for fitting a support rod 26 is formed to extend along the lengthwise direction of the main body 22. A plurality of pin insertion holes 27 are formed on the side surface of the jaw portion 24. Fitting jigs made up from a pin 30 and a stopper 40 is removably fitted in this pin insertion hole 27. The support rod 26 is removably fitted in the engagement notch 25.
