The medical resin hollow needle 1 has a puncture portion 10 at its distal end, and has a hub portion 5 attachable to a luer taper nozzle of a medical device at its proximal end. Then, the puncture unit 10 has a puncture end portion 2 having a solid puncture tip 2 a that tapers in a tapered shape toward the distal end, and a hollow portion 3 continuing to the puncture end portion 2 and extending toward the base end side . The hollow portion 3 has an inner cavity 11 communicating with the inside of the hub portion 5 and side holes 7 a, 7 b penetrating the side wall of the hollow portion 3 to communicate the inner cavity 11 and the outside, and the side holes 7 a, 7 b The distal end wall 71 (puncture end portion side portion) of the puncture end portion 2 side extends in the proximal direction toward the outside from the inner cavity.医療用樹脂製中空針1は、先端に穿刺部10を有し、基端に医療用具のルアーテーパーノズルと装着可能なハブ部5を備える。そして、穿刺部10は、先端に向かって、テーパー状に縮径する中実穿刺端2aを有する穿刺端部2と、穿刺端部2と連続し、かつ基端側に延びる中空部3とを備える。中空部3は、ハブ部5内と連通する内腔11と、中空部3の側壁を貫通して内腔11と外部とを連通する側孔7a,7bとを有し、側孔7a,7bの穿刺端部2側の先端壁71(穿刺端部側部分)は、内腔から外部に向かって基端方向に延びている。
