PURPOSE:To readily obtain a tacky tape having improved adhesive force, by passing a film substrate having a tacky agent layer containing microcapsules containing a crosslinking promoter and succeeding substrate through pressure rolls just after superposing both and completing curing reaction. CONSTITUTION:A film substrate coated with a tacky agent containing microcapsules containing a crosslinking promoter is wound on a core. In the process, the previously wound film substrate and the succeeding film substrate are passed through pressure rolls just after superposing both to break the above- mentioned microcapsules and complete curing reaction. Thereby the aimed tacky tape is obtained. Furthermore, the size of the afore-mentioned microcapsules is preferably about 1-30mu.
