The present invention relates to a method for producing titanium oxide particles, comprising a step of producing a mixed solution by mixing a hydrolysis product of a titanium alkoxide or a titanium metal salt and a compound having a five-membered ring containing nitrogen and a step of generating titanium oxide fine particles by heating and pressurizing the mixed solution, titanium oxide particles produced by the same production method, a dispersion solution of titanium oxide particles produced using the same titanium oxide particles, titanium oxide paste, a titanium oxide film, and a dye-sensitized solar cell.
