When used as an adhesive, a propylene-based polymer (A) capable of pellet handling that adheres to various adherends to express necessary initial adhesive force and does not cause adherent contamination, and a pellet comprising the propylene-based polymer (A), It provides an adhesive comprising the propylene-based polymer (A).n n n 65 to 80 mol% of structural units derived from propylene, 5 to 10 mol% of structural units derived from ethylene, and 15 to 25 mol% of structural units derived from α-olefins having 4 to 20 carbon atoms (wherein The sum total of the structural unit, the structural unit derived from ethylene, and the structural unit derived from a C4-20 alpha-olefin is set to 100 mol%, and the amount of heat of crystal melting measured by the DSC method is 5-45 (J / g And a propylene polymer (A) and a propylene polymer (A). |
