<p><P>PROBLEM TO BE SOLVED: To provide a solar battery module which is equipped with a power lead pull-out structure improved in electric insulation reliability and workability, has fire resistance and is inexpensive; and to provide its manufacturing method. <P>SOLUTION: In the solar battery module, a power lead member 116 of positive and negative poles of a solar battery is led into a terminal box composed of a hollow body structure 128 made of electric insulating materials via a rear protection member, and electrically connected to a terminal 124 of an external connecting cable separately led into the terminal box. The rear protection member has at least a conductivity reinforcing layer 111 composed of a conductive material equipped with a through hole 117 through which the power lead member is passed, and the hollow body structure is equipped with a lead hole 118 for passing through the power lead member which faces the through hole and aligns its center. Further, 1/2 of a difference (D1-D2) between a diameter (D1) of the through hole and a diameter (D2) of the lead hole is equipped with at least a dimension of or longer than a predetermined electric insulation distance between the power lead member and the conductivity reinforcing layer. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
