A method of manufacturing a ceramic film includes forming the ceramic film
by crystallizing a ceramic raw material liquid which includes a first raw
material liquid and a second raw material liquid. The first raw material
liquid and the second raw material liquid are different types of liquids,
the first raw material liquid is a raw material liquid for producing a
ferroelectric, the second raw material liquid is a raw material liquid
for producing an oxide such as an ABO-type oxide, a solvent included in
the first raw material liquid and a solvent included in the second raw
material liquid have different polarities, and the ceramic film is formed
in a state in which the first raw material liquid and the second raw
material liquid are phase separated so that first crystals formed of the
first raw material liquid are intermittently formed in a surface
direction of the ceramic film and second crystals formed of the second
raw material liquid are formed so as to interpose between the first
crystals.
