An electric power transmission apparatus of a sunroof for a vehicle, the electric power transmission apparatus comprising:

• a moving glass mounted with an electric generator, and configured to slide between an opened position and a closed position;
• an upper electric conduction device coupled at a lower side of the moving glass, and including a moving spring that is electrically connected with the electric generator and coupled to protrude downward;
• a front electric conduction device including a front support portion that is a nonconductor, and a close spring that comes into contact with the moving spring when the moving glass moves to the closed position;
• and
• a rear electric conduction device including a rear support portion that is a nonconductor, and an open spring that comes into contact with the moving spring when the moving glass moves to the opened position,
• wherein when the moving glass slides between the opened position and the closed position, the moving spring is earthed while coming into line-to-line contact with the front support portion or the rear support portion, and then comes into contact with the close spring or the open spring so that electricity is conducted.
