23 and continuously rubs the tip end of the electrode 10 the tip end of the electrode 10 is rubbed by the brush body 25 so that the extraneous substances adhered thereon are removed without difficulty the tip end of the electrode 10 is prevented from asymmetric deformation because the tip end is rubbed axis symmetrically and is prevented from scratching because there is no use of an edge tool furthermore the cleaning operation is easily achieved simply by pressing the electrode 10 into the brush body 25 the electrode 10 is recovered without difficulty so as to be reused until it has been worn off therefore the cleaning apparatus contributes to a suppression of production costs a second embodiment of the present invention is described hereinafter with reference to fig2 according to the second embodiment in contrast with the first embodiment the brush body 25 is fixed and the electrode 10 rotates the electrode 10 is fixed to the chuck 23 at the proximal end thereof and rotates in connection with the rotation axis 22 the supporting container 24 filled with the brush body 25 may be supported appropriately with hands and the like the electrode 10 when cleaning is detached from the optical fiber fusion splicer and the proximal end thereof is fixed to the chuck 23 and the chuck 23.
