PROBLEM TO BE SOLVED: To provide a self-adhesive with which occurrence of remaining adhesive and peeling failure can be prevented even with the elapse of time after the self-adhesive is subjected to outdoor exposure or storage at high temperature and which has good adhesive property, a self-adhesive sheet using the self-adhesive, a self-adhesive sheet used for a surface protection purpose, and a method for producing those self-adhesive sheets. SOLUTION: The self-adhesive contains a crystalline propylene-based copolymer including, as copolymerization components, propylene, a 4-12Cα-olefin and ethylene, wherein the propylene-based copolymer exhibits an endothermic peak of 1.1-24.0 J/g as measured with a differential scanning calorimeter (DSC) in a temperature range of 0-200°C.
