Abstract
Disclosed is a method of manufacturing a composite member in which a conductive portion is selectively formed in an insulator. The method comprises the steps of forming a photosensitive composition layer containing a compound forming an ion-exchange group upon irradiation with light having a wavelength not shorter than 280 nm within or on the surface of an insulator, exposing selectively the photosensitive composition layer to light having a wavelength not shorter than 280 nm, forming an ion-exchange group in the exposed portion, and bonding a metal or metal ions to the ion-exchange group formed in the exposed portion of the photosensitive composition layer.
