Abstract: A method of producing a functional device according to the present invention includes, in this order: the functional solid material precursor layer formation step of applying a functional liquid material onto a base material to form a precursor layer of a functional solid material; the drying step of heating the precursor layer to a first temperature in a range from 80° C. to 250° C. to preliminarily decrease fluidity of the precursor layer; the imprinting step of imprinting the precursor layer that is heated to a second temperature in a range from 80° C. to 300° C. to form an imprinted structure on the precursor layer; and the functional solid material layer formation step of heat treating the precursor layer at a third temperature higher than the second temperature to transform the precursor layer into a functional solid material layer.
