To provide a fuel vapor supply device quickly supplying fuel vapor and supplying a sufficient amount of the fuel vapor.

When an engine is stopped by idle stop control at an intersection for instance, fuel is injected into a storage tank 40 by a fuel injection valve 41. At this time, when the atmosphere in the storage tank 40 is warmed by engine cooling water of a heat insulating tank 50, the fuel evaporates in the atmosphere of high temperature and the fuel vapor having a large proportion of low boiling point components is generated in the storage tank 40. After that, when engine start is requested, a purge valve 61 is opened and the fuel vapor is supplied to an intake passage 23 via supply piping 60.
