Abstract: 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.

Abstract: Titanium oxide particles of the present invention include octahedral-shaped particles, in which each particle of the octahedral-shaped particles has line segments each of which connects two apexes which face each other and has a maximum value of the line segments, an average value of the maximum values is 300 nm or more and 1,000 nm or less, and a value (the average value of the maximum values/BET-converted average particle diameter) obtained by dividing the average value of the maximum values of the line segments by an average particle diameter converted from a BET specific surface area is 1.0 or more and 2.5 or less.
