OPTICAL WIRING SUBSTRATE, MANUFACTURING METHOD OF OPTICAL WIRING SUBSTRATE AND OPTICAL MODULE

摘要

An optical wiring substrate includes an insulation layer including a resin, and a conductor layer formed on the insulation layer and including a metal and an inclined surface inclined relative to an optical axis of an optical fiber. A first wiring pattern and a second wiring pattern are formed in the conductor layer, the first wiring pattern including a first connecting part to which a first electrode of a photoelectric conversion element is connected, and the second wiring pattern including a second connecting part to which a second electrode of the photoelectric conversion element is connected. A distance between the first wiring pattern and the second wiring pattern is narrowest between the first connecting part and the second connecting part. A distance between the first connecting part and the second connecting part is less than a dimension of the conductor layer in a thickness direction thereof.
