To prepare a wiring board and an electronic circuit having a proper fine wire pattern and a proper narrow gap between the patterns that use a coating material, and to lower the cost of an organic thin-film electronic device and the electronic circuit, since they become realizable through a development of a printing technique.
The wiring board with a field effect transistor comprises a plurality of trenches arranged in parallel; a common trench communicating the plurality of trenches at one of their ends; a metal layer formed at the bottom of the plurality of trenches; and an electrode layer, connected with the metal layer and formed at the bottom of the common trench, and the electrode layer provided in the common trench constitutes a source electrode or a drain electrode.
