PROBLEM TO BE SOLVED: To provide a solar-cell power collection sheet which is used for internal wiring in a solar cell module and makes it possible to prevent short circuit between an element as P-pole on a non-light-receiving surface side and a wiring section corresponding to N-pole, and suppress impact.SOLUTION: A solar-cell power collection sheet 2 for internal wiring in a solar-cell module is disposed on the back side of a back-contact-type solar-cell element 1. A circuit 22 having a wiring section 221 made of metal and a non-wiring section 222 is formed on the surface of a resin base material 21. An insulation layer 231 and a sealing layer 232 are sequentially formed on the circuit 22. In order to electrically connect electrodes 41 and 42 on a non-light-receiving surface side in the solar-cell element 1 with the wiring section 221 corresponding to the electrodes 41 and 42 through the insulation layer 231 and the sealing layer 232, a contact recessed part 24 where the wiring part 221 is exposed is formed on the insulation layer 231 and the sealing layer 232 on the wiring part 221. |
