PROBLEM TO BE SOLVED : To provide an aqueous pressure-sensitive adhesive composition which can be suitably used for manufacturing a pressure-sensitive adhesive sheet showing a good adhesion property to a smooth- or rough-surface adherend, especially a re-releasable pressure-sensitive adhesive sheet which can be re-released from the adherend and can be repeatedly attached and released. SOLUTION : The pressure-sensitive adhesive composition contains at least two adhesive spherical particulates comprising at least one spherical particulate (A) having a melting temperature of >60°C and at least one spherical particulate (B) having a melting temperature of ≤60°C. A manufacturing method of the pressure-sensitive adhesive sheet uses the composition. The pressure-sensitive adhesive sheet is manufactured through the method using the composition.
