摘要：
Provided is a crosslinked elastomer that can easily be decrosslinked. The crosslinked elastomer is obtained through crosslinking of a diene elastomer that has a vinyl bond content of 30 mass% or less and a weight-average molecular weight of 1,000 or more. The crosslinked elastomer includes a diboronic acid ester skeleton unit represented by a specific general formula (1) at a crosslinking site.
