PROBLEM TO BE SOLVED: To provide a method for producing a pseudo-bonding paper having a stable adhesive property and a re-releasability. SOLUTION: In the method for producing the pseudo-bonding paper, a coating solution which includes a non-releasable adhesive base material, fine particle filler and a nonionic surfactant, not bonding in the usual condition but bonding after applying a specific condition and re-releasable after bonding, is applied to a base paper with forming a mono-layered freely falling vertical curtain of the coating solution and continuously running the paper base in a crossing direction of the curtain. The coating solution characteristically manifests <=40 mN/m of a static surface tension and includes precipitated silica having 1 to 8μm of the average diameter of the coagulated particle measured by Coulter counter method and >=200 ml/100 g of linseed oil absorption measured by JIS K 5101 as the fine particle filler in amount of 20 to 50 wt.% in the coating solution.
