PROBLEM TO BE SOLVED: To form a pressure sensor made of a sapphire at a low cost without impairing the characteristics of the sapphire. SOLUTION: A method for manufacturing the pressure sensor comprises the step of connecting a cover plate (a plate member made of the sapphire) made of the sapphire to a chip 110 of the pressure sensor fixed with a buffer member 120, by using a coating solution obtained by adding a titanium dioxide to an aqueous solution of a Boehmite (AlO(OH)) of a hydroxide ore of an aluminum.
