Abstract: An interface configured to be brought into contact with a channel chip and to connect a channel of the channel chip with an external device. The interface includes an elastic first member and a second member supporting the first member. The first member includes a first channel for communicating with the channel and a second channel for communicating with the external device. The first channel and the second channel communicate with each other, and the second channel is disposed in such a way that a distance from the center of gravity of the channel chip to the second channel increases from the end of the second channel on the first channel side toward the end of the second channel on the external device side when the interface is viewed in plan view while the interface is in contact with the channel chip.

Abstract: Provided is a fluid handling device in which a fluid can fill not only a specific flow path but also a connection flow path branching from the specific flow path. The fluid handling device includes a main flow path, a first flow path, and a first connection flow path connecting the main flow path to the first flow path. The main flow path is a flow path into which a fluid A is introduced to fill the main flow path and the first connection flow path, and when the fluid A introduced into the main flow path flows from the main flow path into the first connection flow path, a Laplace pressure PL1 acting at an interface between the fluid A and a fluid B filling the first connection flow path in advance satisfies Condition 1. Condition 1 is PC>PL1, where PC is the internal pressure in a branching portion of the main flow path branching to the connection flow path, and PL1 is the Laplace pressure when the dynamic contact angle θ of the fluid A introduced from the main flow path into the connection flow path relative to an inner wall of the connection flow path is set to a value less than π.
