There is disclosed a method of producing a solar cell module comprising
the steps of: mounting a body to be laminated onto a tabular member,
carrying in the body to be laminated along with the tabular member onto a
heated mounting board; heat-bonding the body to be laminated by pressing
with an expanding unit; carrying out the body to be laminated along with
the tabular member from the mounting board after parting the expanding
unit from the body to be laminated; and separating the body to be
laminated from the tabular member. By using the method, a temperature of
the body to be laminated does not increase rapidly and a foaming
phenomenon is suppressed, thereby allowing manufacturing of the solar
cell module with a high yield.
