A process for producing a specific titanium-containing silicon oxide catalyst having a specific average pore diameter, a specific a pore diameter distribution and a specific pore volume per unit weight, which comprises the following first to second steps: first step: a step of obtaining a solid containing a catalyst component and a template by mixing and stirring a silica source, a titanium source and, as the template, the quaternary ammonium ion, wherein an amount of an alkali metal in the mixture prepared is within a range of the following expression (II) or (III), <DF NUM="(II)">alkali metal/titanium </= 3(mol/mol) </DF> <DF NUM="(III);">alkali metal/ÄNR<1>R<2>R<3>R<4>Ü<+> </= 0.3(mol/mol) </DF> and second step: a step of removing the template from the solid prepared in the first step.
