Abstract
In a flow path member joining structure for enabling a liquid to flow by attaching, to a first member having a first flow path, a second member having a second flow path and aligning the first flow path and the second flow path with each other, the first flow path is opened to a first end face of the first member, the second flow path is opened to a second end face of the second member, and the second end face is formed as an inclined surface inclined from an opening of the second flow path toward a periphery.

A flow path member joining structure for enabling a liquid to flow by attaching, to a first member having a first flow path, a second member having a second flow path and aligning the first flow path and the second flow path with each other, wherein:
- the first flow path is open toward a first end face of the first member,
- the second flow path is open toward a second end face of the second member, and
- the second end face is formed as an inclined surface inclined from an opening of the second flow path toward a periphery thereof.
A column that is attached to a column attaching/detaching unit having a pair of pedestals facing each other, communication holes respectively open toward the pair of pedestals, and liquid passage flow paths communicating with the respective communication holes, the column comprising:
- two end faces respectively facing the pair of pedestals;
- liquid passage holes respectively opened at centers of the two end faces;
- and
- a column flow path connecting the liquid passages holes, wherein
- each of the two end faces is formed as an inclined surface inclined from the corresponding liquid passage hole toward a periphery thereof.
