PROBLEM TO BE SOLVED: To provide an organic field-effect semiconductor device being capable of making the orientation of the constitutional molecules of an organic semiconductor layer dense and having a high performance, and to provide a manufacturing method for the semiconductor device. SOLUTION: The organic field-effect semiconductor device 1 has a first electrode 3 and a second electrode 5 formed on a base body 2, the organic semiconductor layer 7 formed between these electrodes, and a third electrode 9 applying an electric field to the organic semiconductor layer 7 through an insulating film 8. The base body 2 is composed of the quality of the material expanded and contracted by an external stimulus, and the organic semiconductor molecules 4 of the organic semiconductor layer 7 are made dense, desirably brought into contact mutually and oriented under the contracted state of the base body 2. Accordingly, a carrier mobility between the first electrode and the second electrode can be increased, and an on current value and the characteristics of an on/off ratio are improved.
