A laser or a metal needle is used to divide a light absorbing layer (3) and a buffer layer (4) by removing the light absorbing layer and the buffer layer. Next, laser is applied to a portion containing the divided end portion so as to thermally melt the end portion and perform laser anneal to make the substantially vertical end portion into an inclined state. Thus, the thickness of TCO accumulated on the inclined end portion is substantially equal to the thickness of TCO formed on the upper surface of the light absorbing layer. |
