Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a confidential post card sheet at a low cost in which even a large-sized continuous type dry sealer and even a small-sized sheet type dry sealer can be used and laser printer printing suitability is excellent. SOLUTION: The confidential post card sheet is equipped with a base material sheet and an adhesive layer which contains both an adhesive and an adhesive force-controlling agent on the face of at least one side of the base material sheet. The adhesive layers are faced so that the mutual faces are overlapped and adhesive force is 120-200 g/25 mm when contact bonding is performed in such the condition that contact bonding speed is 5 m/minute. Also, when contact bonding is performed in such the condition that contact bonding speed is 50 m/minute, adhesive force is 95-70% of the value in the case of 5 m/minute.
