A flexible device (1) has: an insulating substrate (2); a source electrode (3), a drain electrode (4), and an extended gate electrode (5) that are formed with spaces therebetween on a surface of the insulating substrate (2); a channel (6) disposed between the source electrode (3) and the drain electrode (4); and a gate dielectric (7) formed so as to cover the entire channel (6) and a portion of the extended gate electrode (5). The insulating substrate (2) is a flexible thin film having light transmittance, the extended gate electrode (5) is a carbon material thin film having biocompatibility and light transmittance, the channel (6) is an organic semiconductor thin film, and the gate dielectric (7) is an ionic liquid or an ion gel. |
