Pressure sensitive transfer correcting tape disclosed herein has improved resistance to bleeding from a line drawn with a ballpoint pen or the like. The pressure sensitive transfer correcting tape may include a release substrate including paper or a plastic film and a pressure sensitive transfer layer including at least a correcting and covering layer and a pressure sensitive adhesive layer laminated sequentially on one side of the release substrate. The correcting and covering layer contains porous silica and acid-modified rosin. In some examples, the oil absorption of the porous silica is preferably in a range of from 100 to 320 ml/100 g, and the acid value of the acid-modified rosin is preferably 180 mg KOH/g or more.
