NOVELTY - Manufacturing a solar cell module (100) comprises forming a pair of first slits and a second slit in the rear-surface-side protection member to form a pair of movable portions on both sides of the second slit; opening each of the pair of movable portions; performing an insulating treatment on at least a part of the metal layer exposed to the surface of each of the pair of movable portions; and sealing a solar cell (10) between a light-receiving-surface-side protection member (13) and the rear-surface-side protection member.    USE - The method is useful for manufacturing a solar cell module including a rear-surface-side protection member having a metal layer sandwiched between resin layers (claimed).    ADVANTAGE - The present invention provides a manufacturing method of a solar cell module capable of securing electrical insulation between a metal layer of a rear-surface-side protection member and an output lead.    DETAILED DESCRIPTION - Manufacturing a solar cell module (100) including a rear-surface-side protection member (14) having a metal layer sandwiched between resin layers, the method comprises forming a pair of first slits and a second slit in the rear-surface-side protection member to form a pair of movable portions on both sides of the second slit, the second slit extending between and communicating with the pair of the first slits; opening each of the pair of movable portions; performing an insulating treatment on at least a part of the metal layer exposed to the surface of each of the pair of movable portions; and sealing a solar cell (10) between a light-receiving-surface-side protection member (13) and the rear-surface-side protection member, where one end portion of an output lead (12) is drawn out from between the pair of movable portions, the output lead being configured to draw electric power from the solar cell. An INDEPENDENT CLAIM is a solar cell module comprising: a light-receiving-surface-side protection member, a rear-surface-side protection member having a metal layer sandwiched between resin layers, solar cells arranged between the light-receiving-surface-side protection member and the rear-surface-side protection member, and an output lead drawing the electric power generated by the solar cells to its outside, where the rear-surface-side protection member includes a first portion partially surrounded by a slit and a second portion partially surrounded by a slit, the output lead is drawn out from between the first portion and the second portion, and an insulating member is located between the output lead and a part of an outer circumference of the first portion facing to the output lead, and between the output lead and a part of an outer circumference of the second portion facing to the output lead.
