<p>Provided is a grooving tool for a thin film solar cell in which when a cutting edge is worn, it can be easily replaced with a new cutting edge without exchanging the grooving tool itself, and integrated thin film solar cells can be manufactured at a high yield. A plurality of cutter blade areas having cutting edges that are directed substantially in the tangential directions are spaced from one another at equal distances in the circumferential direction on the outer peripheral portion of a disc-like body (81) which is rotatably and fixably attached to a holder (9) of a scriber, wherein one of the cutting edges is used to form a groove.</p> |
