NOVELTY - The method involves forming relief hole in wiring sheet (21) in direction orthogonal to first and second wiring (28) formed in insulating base material (22), corresponding to place where p-type and n-type electrodes are connected with respective wirings. Back-contact type photovoltaic cells (1) are mounted in connection place aligned in wiring sheet. Water permeation prevention layer is joined with photovoltaic cell using solder, while contacting heater tool (203) to wirings at preset time interval, and pressing wirings to respective p-type and n-type electrode.    USE - Method for manufacturing solar cell module of solar energy power generation system.    ADVANTAGE - The solar cell module can be manufactured effectively, since the deterioration of the sealing material can be prevented by joining water permeation prevention layer with photovoltaic cell using solder, while contacting heater tool to wirings at preset time interval, and pressing wirings to respective p-type and n-type electrode. The slot-form relief hole is formed in the insulating base material of portion heated with the heater tool of the wiring sheet, so that the insulating base material is not heated directly and resin film with low heat resistance can be adopted as this insulating resin, thus the manufacturing cost of the solar cell module can be reduced.    DETAILED DESCRIPTION - The solder is supplied to p-type electrode and n-type electrode of back-contact type photovoltaic cell. The first wiring and second wiring are formed on insulating base material. The predetermined spacing is formed between first wiring that is connected to p-type electrode formed on straight line and second wiring that is connected to n-type electrode formed on straight line. An INDEPENDENT CLAIM is included for manufacturing apparatus of solar cell module.
