To provide: a method of manufacturing a solar battery module capable of simultaneously and continuously carrying out serial interconnection and sealing of solar battery cells by a simpler method as compared with a conventional one, reducing generation of microcracks in a solar battery cell, shortening cycle time and decreasing a manufacturing space; a device for manufacturing solar battery module; and a coating material which can be used for the manufacturing method.

A method of manufacturing a solar battery module includes: a step for placing a solar battery cell 110 on a first coating material 108A having a protecting material 102A, a sealing material 104A, and wiring 106A; and a step for supplying a second coating material 108B having a protecting material 102B, a sealing material 104B, and wiring 106B. Between the adjacent solar battery cells 110, a first end portion 109A of the wiring 106B and a second end portion 109B of the wiring 106A are opposite to each other, and then, by a step for pressurizing and heating the coating materials 108A and 108B, the adjacent solar battery cells 110 are electrically connected and the solar battery cells 110 are sealed.
