ABSTRACT:
An optical-pickup slider is characterized in that a light-transmitting-property substrate is bonded to a surface of a layer having a tapered through hole, on which surface a larger opening of the tapered through hole exists. Thereby, it is possible to prevent the layer having an aperture from being destroyed. A method of manufacturing the optical-pickup slider comprises the steps of a) making a tapered through hole in a layer layered on a first substrate and having a thickness smaller than that of the first substrate; and, after bonding a light-transmitting-property substrate to a surface of the layer, removing the first substrate so as to expose an aperture at a tip of the tapered through hole.
