Summary:PROBLEM TO BE SOLVED: To provide a dispensation head which can be mounted with any one of a large-diameter chip and a small-diameter chip having mutually different diameters, and to provide a dispensation device having the same.SOLUTION: A dispensation head 16 is arranged in which nozzles extending downward are arranged in vertical and horizontal directions. The dispensation head 16 has large-diameter nozzles 18b and small-diameter nozzles 18s having mutually different diameters as nozzles arranged therein. A center interval d between the adjacent nozzles of a large-diameter nozzle group BNG constituted by the large-diameter nozzles 18b is the same as a center interval d between the adjacent nozzles of a small-diameter nozzle group SNG constituted by the small-diameter nozzles 18s. In the large-diameter nozzle group BNG and the small-diameter nozzle group SNG, nozzle positions are shifted in the vertical and horizontal directions, and arrangement areas BNA, SNA of both of the nozzle groups overlap each other by shifted to each other.SELECTED DRAWING: Figure 3 【課題】径が互いに異なる大径チップ、小径チップの何れであっても装着することができる分注ヘッド、およびそれを備えた分注装置を提供する。【解決手段】分注ヘッド16は、下方へ延び出すノズルが縦・横に整列して配設されている分注ヘッド16である。分注ヘッド16には、ノズルとして、互いに径が異なる大径ノズル18bと小径ノズル18sとがそれぞれ配列されている。大径ノズル18bで構成される大径ノズル群BNGの隣り合うノズル同士の中心間隔dと小径ノズル18sで構成される小径ノズル群SNGの隣り合うノズル同士の中心間隔dとが同じである。そして、大径ノズル群BNGと小径ノズル群SNGとでは、ノズル位置が縦・横にずれていて、両ノズル群の配置領域BNA、SNAがずれて重なっている。【選択図】図3
