Abstract
A polypropylene-based adhesive containing a polypropylene-based resin (A') prepared by reducing the weight-average molecular weight of a polypropylene-based resin (A) by decomposition, in which the melting endotherm (ΔH-D) of the polypropylene-based resin (A) is 0 J/g or more and 80 J/g or less, as obtained from a melting endothermic curve drawn by holding a sample at −10° C. for 5 minutes in a nitrogen atmosphere followed by heating it at 10° C./min using a differential scanning calorimeter (DSC).
