A polyamide elastomer obtained by reacting at least components (a), (b) and (c) below, wherein the number average molecular weight of component (a) is 4,000 to 10,000, inclusive. Component (a) comprises at least one compound represented by general formula (1). (In the formula, each R1 is, independently, a linear saturated hydrocarbon group with one or more carbons, and n represents a real number of 0 or above. When two or more repeating units containing R1 are included, the sum of each repeating unit containing R1 is taken as being n.) Component (b) comprises at least one compound represented by general formula (2). (In the formula, R2 is represents a direct bond or a linear saturated hydrocarbon group with one or more carbons.) Component (c) comprises at least one compound represented by general formula (3). (In the formula, each R4 independently represents a saturated hydrocarbon group with one or more carbons, and m represents a real number of 1 or above. When two or more repeating units containing R4 are included, the sum of each repeating unit containing R4 is taken as being m.) |
