A solar cell module includes a connecting member to be passed through a coating of a cable for electrically connecting a plurality of solar cell modules and to be electrically connected to a core wire of the cable. The solar cell module is connected to the cable by pressing the connecting member of the solar cell module to pass through the coating of the cable and come into contact with the core wire of the cable. An electrical connection of the solar cell module with a ground wire is made by a similar technique.
