SOLAR CELL MODULE, MANUFACTURING METHOD OF SOLAR CELL MODULE, REEL WITH TAB LINE WOUND THEREABOUT

PROBLEM TO BE SOLVED: To enhance connection reliability when connecting a tab line and the electrode of a solar cell by using a conductive adhesive.SOLUTION: The solar cell module comprises multiple solar cells 2, and a tab line 3 connected onto electrodes 11, 13 formed, respectively, on the front surface of the solar cell 2 and the back surface of an adjoining solar cell 2 through a conductive adhesive 17 containing spherical conductive particles 23 and interconnecting the multiple solar cells 2. Protrusions and recesses 18 are formed on one surface of the tab line 3 in contact with the conductive adhesive 17. Average height (H) of the protrusions and recesses 18 and the average particle size (D) of the conductive particles satisfy a relation D≥H.
