An optical pickup device and an optical information recording and/or reproducing apparatus which make it possible to stably secure electrical wires at predetermined locations in a slide base when forming the slide base by covering a surface of a circuit core, which functions as an electrical wiring, with an external base portion, with a portion of the circuit core being exposed. The slide base includes a circuit core and an external base portion. The circuit core is an electrical conductor forming an electrical circuit for supplying electricity to a bi-axial actuator. The external base portion is an insulating member for covering a surface of the circuit core with a portion of the circuit core being exposed. An external frame is continuously formed with the outer side of the circuit core and is cut off from the circuit core after covering the circuit core with the external base portion by injection molding. The external frame has at least two positioning holes for positioning the external frame at a die, used for the injection molding, when covering the circuit core. With the circuit core being positioned at the die by fitting at least two positioning pins disposed at the die to the at least two positioning holes of the external frame, the external base portion is molded integrally with the circuit core by the injection molding.
