摘要： 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 open toward a first end face of the first member, and an enlarged diameter portion whose inner diameter gradually increases toward the first end face is formed at an end of the first flow path, and the second flow path is open toward a second end face of the second member.

摘要： A liquid chromatography column comprising: a column tube including a flow path that runs therethrough in an axial direction of the column tube and that is filled with a filler; a filter unit that is mounted at an axial direction end of the column tube to trap the filler inside the flow path; and a cap that includes a through hole communicated with the flow path through the filter unit and that is mounted at the column tube, wherein a gap, which is a space into which the filler overflowing from the flow path can escape when the cap is being attached to the column tube, is formed at an outer side of a contact surface at which the column tube and the filter unit contact each other.

摘要： 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.
