To provide a projection sheet which effectively avoids the possibility that a projection is come off a base material sheet when it is used and can be used in an excellent state over a long period of time, and a method of manufacturing the projection sheet.

In a projection sheet 1 where the front face of a base material sheet 2 is provided with plural projections 3 in parallel, core bodies 4 in contact with the rear face of the base material sheet 2 are projected together with the base material sheet 2 toward the front face side to configure the plural projections 3, so that the come-off of the projections 3 can be prevented by the action of the base material sheet 2 covering the front faces of the core bodies 4.
