Calcium cobaltite (Ca 3 Co 4 O 9 ; CCO349) films with a c ‐axis texture and a thickness of 60 μm were fabricated by aerosol deposition (AD). The films exhibited superior characteristics to those grown by other methods. The pole figure measurements indicated that almost 65% of the films had their c ‐axis tilted from the surface normal by 30°. The Seebeck voltage and resistivity of the films in the measurement range between room temperature and 900 K were 175 μV/K and <20 mΩ·cm, respectively. Based on these results, the AD‐CCO349 film is a promising material for thermoelectric generation.
