<P>PROBLEM TO BE SOLVED: To provide a solar cell power collection sheet capable of preventing short circuit caused by solder when joining a conductive pattern provided on the solar cell power collection sheet and soldered materials through soldering. <P>SOLUTION: A solar cell power collection sheet 1 has a belt-like conductive pattern 3 formed on the surface of a resin base material 2, the conductive pattern 3 being formed of metal foil of a predetermined thickness. The solar cell power collection sheet 1 is characterized in that the conductive pattern 3 consists of a plurality of conductive raised portions and non-conductive recessed portions, wherein the recessed portions being located between the conductive raised portions, having surface side of the resin base material 2 as its bottom portion, and sharing sides of the conductive raised portions as its side walls, and that the side walls of the non-conductive recessed portions form an inverted taper shape extending from the surface side of the resin base material 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
