A solar battery cell serving as a member to be protected is sandwiched between protective films for lamination and disposed in a press-type laminating device. The protective films are then heated, and when the temperature of the protective films becomes a first temperature which is equal to or higher than the softening point of the protective films, pressing of the protective films and the solar battery cell is started. Then the protective films are held at a second temperature (target temperature) that is higher than the first temperature, in a state in which the protective films and the member to be protected are pressed.
