Abstract
A bioinert piping (1) that has a flow path (2) provided inside and a main body portion (10) between end portions (8, 8) includes a resin tube (4) that forms an inner wall of the flow path (2) over an entire length of the flow path (2), and a metal tube (6) that accommodates the resin tube (4) inside so as to cover the outer peripheral surface of the resin tube (4) over at least an entire length of the main body portion (10). The metal tube (6) is plastically deformed toward an inner side so that the outer peripheral surface of the resin tube (4) and an inner peripheral surface of the metal tube (6) are in liquid-tight contact with each other.
