1. An apparatus for bonding two optical disc substrates together by joining the optical disc substrates together with an adhesive which is liquid and by curing the adhesive, which comprises an adhesive-supplying nozzle which supplies the adhesive onto at least one of the optical disc substrates, and is a first electrode, an adhesive storage tank which stores the adhesive, and supplies the adhesive to the adhesive-supplying nozzle, an electrode means which is a second electrode and is placed in contact with or in the vicinity of the surface of the optical disc substrate which is opposite to the surface which faces the adhesive-supplying nozzle, an electric power supply for generating an electric field between the electrode means and the adhesive-supplying nozzle, and a joining apparatus for joining one of the optical disc substrates, onto at least one of which the adhesive is supplied, and another one of the optical disc substrates, wherein the adhesive-supplying nozzle is connected to a terminal of the electric power supply and a ground potential, and the electrode means is connected to another terminal of the electric power supply.
