PROBLEM TO BE SOLVED: To provide a pipet tip whose tip part is not bent owing to a thickness difference of the peripheral direction. SOLUTION: This pipet tip 1 consists of an almost conical tube-shaped housing part 2 having a small hole 2x formed at the tip for sucking and discharging a liquid and a mounting part 3 formed successively on the base end of the part 2 for mounting a sucking nozzle. A plurality of inner peripheral conical surfaces 22a-22f each having the set taper angle and conic length are formed on the inner peripheral surface 22 of the part 2. Valleys B1, B2 and peaks P2, P3, P4 are formed successively on the crossing sides of the respectively adjacent surfaces 22a-22f. The wall thickness formed between the outer peripheral surface 21 and the inner peripheral surface 22c or 22e is made thinner gradually as it goes toward the valley B1 or B2. COPYRIGHT: (C)2003,JPO
