Abstract
The present invention provides a production method for indene, comprising a dehydrogenation step of obtaining a reaction product containing indene by contacting a raw material composition containing indene with a dehydrogenation catalyst, wherein the dehydrogenation catalyst comprises a support containing aluminum, and a group 14 metal element and platinum supported on the support, a content of the platinum in the dehydrogenation catalyst is 0.6 to 2.5% by mass based on a whole amount of the dehydrogenation catalyst, and an atomic ratio of the group 14 metal element to the platinum in the dehydrogenation catalyst is 4.0 to 20.0.
