ABSTRACT:
A device mounting board for a device to be mounted on, comprising: a substrate; and a laminated film composed of a plurality of insulating layers formed on one side of the substrate. Here, any of the second and subsequent insulating layers from the substrate is a photosolder resist layer containing a cardo type polymer. The photosolder resist layer has a thickness smaller than that of the insulating resin film arranged between the photosolder resist layer and the substrate.
