PROBLEM TO BE SOLVED: To stably preserve an oxetane compound useful as a material, etc., for cationic curable resins by preserving the oxetane compound in an atmosphere of an inert gas (except CO2). SOLUTION: An oxetane compound such as a 3-alkyl-3-hydroxymethyloxetane is preserved in a hermetically sealed state or a state in which the infiltration of the outside air is shut off preferably in a container preferably at room temperature in an atmosphere of an inert gas (e.g. nitrogen gas) except gaseous carbon dioxide. Further, a basic compound (e.g. triethylamine) in an amount within the range of preferably 1 wt. ppm to 1% may be present for the above preservation An oxetane compound having >=90% purity (according to a gas chromatography), <=0.5 wt.% moisture content, pH 4.0-7.0 and <=0.5 mgNaOH/g acid value is preferably used.
