PROBLEM TO BE SOLVED: To suppress the damage of a sealing member when a pipette tip is detached. SOLUTION: An inclined part 45 inclined so as to widen an opening upward is formed to a groove end surface part 44. The angleθof inclination of the inclined part 45 satisfies the condition ofα<βand L0<L1 when the taper angle of inclination of a tip part 26 is set toα; the angle of inclination of the tangential line of the lower corner part of a nozzle rib part with the sealing member is set toβ; the distance in a height direction between the position A crossing the side wall of the tip part 26 and the upper end part of the inclined part 45 is set to L0 and the distance in a height direction between the lower and upper end parts of the inclined part 45 is set to L1.
