A method for manufacturing liquid crystal alignment film of the present invention comprises the steps of: aligning a transparent substrate film by rubbing; laminating a surface protective sheet having a release force of 0. A folded braid portion 24 is formed by folding an annular projecting braid portion 23 from its proximal end portion 34 so as to superpose the folded annular projecting braid portion on one insulative sheath 31a. The device is configured so that the magnetic component allows the template member to be affixed to a metal object so that the outer edge andor the window component may be used as a guide for cutting the metal, and allows the component to be removed from the metal when it is no longer needed for cutting.
