PURPOSE: Provided are a microarraying head and a microarrayer for sequencing a large number of biological samples such as DNA fragments or oligonucleotides on substrates. Therefore, a plurality of placing portions for placing spots on substrates can be cleansed surely, and the work of forming spots and the work of cleansing and drying a microarraying head can be carried out simultaneously to produce microarrays extremely efficiently. CONSTITUTION: In the microarraying head for retaining a solution including biological samples, and forming spots of the solution on substrates, the microarraying head comprises: a base portion; and a plurality of placing portions arranged in parallel with one another on the base portion and for placing the solution on the substrates with top ends of the placing portions touching the substrates, wherein a space for supplying cleansing fluid is provided in the base portion so as to extend all over the plurality of placing portions. |
