Titanium-containing solid catalyst

A method for producing an oxirane compound in which an olefin type compound is reacted with an organic hydroperoxide in the presence of a titanium-containing solid catalyst;

• wherein the titanium-containing solid catalyst is obtained by further silylation of a catalyst obtained by at least one method selected from the following (1) to (3):
• (1) a titanium compound is supported on silica having an average pore diameter (D) measured by a mercury pressing method of 5 nm or more and having pore distribution in which at least 60% of pore volume is composed of pores having a pore diameter within the range of D±0.3 D (nm), and is calcined,
• (2) silica is impregnated in water, then dried, and a titanium compound is supported on the silica, then calcined,
• (3) silica is impregnated in a titanium-containing impregnation solution satisfying the following (formula 1), and is calcined:
• A/B≦0.2 (formula 1)
• A:
• mol number of metal titanium in the impregnation solution
• B:
• mol number of a silanol group existing in silica.
