To provide a dye sensitized solar cell for protecting a current collecting line by a simple process, protecting the current collecting line from an electrolyte layer reliably, and generating power for a long time.

The current collecting line 2 is plated, or an oxide layer is formed, thus forming a protective layer 3 easily and protecting the current collecting line 2. The plated film and/or the oxide layer is the uniform and minute protective layer 3, and is protected reliably so that the current collecting line 3 cannot be decomposed by the electrolyte layer 4, thus maintaining power generation performance for a long time.
