Provided are a printed circuit board and a manufacturing method therefor, comprising a lower-clad layer, a groove provided on the lower-clad layer, and an optical fibre for transmitting an optical signal embedded in the groove, wherein the optical fibre comprises micro-optical fibres with a diameter ranging from 500nm to 50um. Since the transmission loss of micro-optical fibres is small, there is no need to perform fluorination on an embedded optical waveguide layer as the prior art, thereby greatly reducing process complexity and reducing the manufacture cost of a printed circuit board. |
