Abstract
A wiring board with an electronic device comprising a plurality of trenches arranged in parallel on a substrate, a common trench communicating the plurality of trenches with each other at one of their ends on the substrate, a metal layer formed at the bottom of the plurality of trenches, and an electrode layer connected with the metal layer and formed on a bottom of the common trench, wherein the electrode layer on the bottom of the common trench constitutes a source electrode or a drain electrode of a field effect transistor, whereby the wiring board and an electronic circuit having a good fine wire pattern and a good narrow gap between the patterns using a coating material can be formed, and a reduction for a cost of an organic thin film electronic device and the electronic circuit can be attained since they can be realized through a development of a printing technique.
