    摘要： A method for manufacturing an olefin through reaction between the same type of or different types of raw material olefins to obtain an olefin having a structure different from the structure of the raw material olefins, the method including using a catalyst containing at least one type of metal element selected from the group consisting of tungsten, molybdenum, and rhenium together with other specific catalysts. In the method, side reactions of a metathesis reaction can be suppressed and the selectivity of a desired product can be increased by facilitating double bond isomerization of raw material olefins. Furthermore, the desired product can be obtained efficiently at a high productivity by maintaining the activity of a metathesis catalyst for a long term and suppressing deterioration of performance of a catalyst (isomerization catalyst) for facilitating double bond isomerization of the raw material olefins.
