1. A structure of a flow cell assembly for a chromatography detector that is used to generate a chromatogram of a sample, comprising:
a capillary extending in one direction;
a housing that houses at least part of the capillary; and
a ferrule that holds the capillary in the housing, wherein the capillary includes
an inner tube formed of a material having a refractive index lower than a refractive index of water, and
an outer tube formed of a material having strength higher than strength of a material of the inner tube and has a constant outer diameter that is equal to or smaller than 5 mm over an entire length of the capillary, and
an entire outer peripheral surface of the inner tube and an entire inner peripheral surface of the outer tube adhere to each other over the entire length of the capillary, and a flow path through which a mobile phase including a sample flows is formed in the inner tube.
