Printed circuit substrate with comb-type electrodes capable of improving the reliability of the electrode connections

A printed-circuit substrate comprising:

• a film-shaped support base having an electrical insulating property and elasticity, the film-shaped support base being provided with a resin mold section for supporting an integrated circuit;
• an integrated circuit supported by said resin mold section;
• a plurality of foil-shaped electric conductors which are connected to the integrated circuit at their base side and which are supported by the support base so as to extend toward the periphery of the support base at their tip side, the conductors being formed on a first surface of the support base, the first surface facing electrodes of an external device;
• exposed portions, which are provided by removing the support base in an intersecting direction of the foil-shaped electric conductors over an entire area of the support base between the integrated circuit and the periphery thereof, so that one portion of each foil-shaped electric conductor is exposed by separating the film-shaped support base supporting the integrated circuit and the periphery thereof;
• and
• supporting exposed electric conductor portions, located on both sides of a set of the exposed portions in a direction orthogonal to the exposed portions, each supporting exposed portion having a width wider than that of each exposed portion.
