Abstract: PROBLEM TO BE SOLVED: To form a catheter having a strength and a large elasticity by letting a specific quantity of aluminum borate whiskers included in a thermoplastic polyimide. SOLUTION: Aluminum borate whiskers by 5-50 pts.wt. are included in 100 pts.wt. polyimide resin having repeated units expressed by the formula. When the quantity of a fiber reinforcement material is less than 5 pts.wt., sufficient elasticity is not provided. When it exceeds 50 pts.wt., fusion viscosity of composition is increased, and extrusion performance becomes bad. In the formula, X denotes a group selected from among a group comprising direct coupling sulfur, or the like Y1 , Y2 , Y3 , and Y4 are each hydrogen, a 1-6C low alkyl group, and R1 is a tetravalent group selected from among non-condensed polycyclic aromatic groups mutually coupled by 4-9C aliphatic groups, or the like. A catheter having a strength and a large elasticity can thus be formed.
