A tissue transplantation resin tip includes a needle tube for eyeball insertion. The needle tube includes a main body portion that extends linearly. A front end portion is bent with respect to the main body portion and extends linearly, with tissue discharging from the front end. The needle tube length is 25 mm to 50 mm, the front end portion cross sectional shape is oval with a major axis Dof 0.8 mm to 1.5 mm and a minor axis Dof 0.5 mm to 1.0 mm. The front end of the front end portion is a bevel surface that extends in a direction substantially perpendicular to the main body portion and has a bevel angle of 50° to 85°. The front end portion hardness is 0.15 N to 0.30 N or less and the center of the needle tube hardness is 0.80 N to 1.50 N.
