Abstract

A circuit substrate includes an electrically conductive layer having electrically conductive patterns formed therein, an insulating layer having a through hole, and a composite layer positioned between the electrically conductive layer and the insulating layer. The through hole is configured for having an electronic component mounted thereon. The composite layer includes a polymer matrix and at least one carbon nanotube bundle embedded in the polymer matrix. One end of the at least one carbon nanotube bundle contacts the electrically conductive patterns, and the other is exposed in the through hole of the insulation layer.
