PROBLEM TO BE SOLVED: To provide a polyamide having excellent drawability and especially suitable for successive biaxial drawing. SOLUTION: The objective polyamide contains a unit composed of a lactam and/or an aminocarboxylic acid, a unit composed of a dicarboxylic acid and a unit composed of a diamine containing norbornanediamine. Concretely, the polyamide contains 50-99.8 mol% lactam and/or aminocarboxylic acid, 0.1-25 mol% dicarboxylic acid and 0.1-25 mol% diamine. Norbornanediamine accounts for 10-100 mol% of the diamine. |
