Thereafter, when the remaining positive photoresist liquid is removed, a pattern of the electrode 20 and the channel 30 is formed. Therefore, the electrode 20 and the channel 30 are formed of the same metal oxide resistor layer 3.

FIG. 3C shows a state in which the nanowire is coated on the metal oxide resistor layer 3. Referring to FIG. 3C, the nanowire is spin-coated on the metal oxide resistor layer 3 to form a nanomaterial layer 4 in the form of a film. Here, the nanowire is a silver (Ag) nanowire, for example.
