Abstract: A terminal box for covering an exposed electrode portion of a photovoltaic element module is disclosed. A part or all of each of the side surfaces of the terminal box comprises an inclined surface.

Abstract: A terminal box which is provided at an electrode-taking out portion of a solar cell module, includes, a side face having a portion for threading an externally power outputting cable, a portion for adopting an internal lead wire extended from the electrode-taking out portion of said solar cell module, and a trunk terminal. A trunk terminal support is connected with the trunk terminal, which is used for electrically connecting the externally power outputting cable with the internal lead wire. A solar cell module provided with the terminal box.

Abstract: A jacket material of electrical conductive leads for electrically connecting solar cell modules to each other is comprised of a polyvinyl chloride type resin containing either one of a polyester type plasticizer, a phosphoric acid ester type plasticizer, a fatty acid ester type plasticizer, and an epoxy type plasticizer, whereby the solar cell modules have excellent performance stability with less deterioration of the electrical conductive leads even when the electrical conductive leads are kept in contact with a base member such as an organic waterproof sheet over a long period.

Abstract: The object of this invention is to provide a solar cell module having a terminal extracting structure for it, with high adhesion workability, high productivity, and high reliability. The solution to this object is a solar cell module wherein a box member having therein an electrical connecting portion between a solar cell element and an outer lead wire is adhered to the solar cell module with a pressure-sensitive adhesive, and a lid member is adhered to the solar cell module with an adhesive so as to cover the box member.
