To provide a fluid handling device capable of stably producing droplet-containing liquid in which droplets of a sample are dispersed in transport fluid, even in a case where the viscosity of the sample is high.SOLUTION: A fluid handling device comprises: a sample flow path for flowing a sample; a transport fluid flow path for flowing transport fluid; a generation unit connected to the sample flow path and the transport fluid flow path, for partitioning the sample with the transport fluid and generating droplet-containing liquid in which droplets of the sample are dispersed in the transport fluid; and a droplet flow path connected to the generation unit, for allowing the droplet-containing liquid to flow therein. When a ratio of a flow rate of the sample flowing through the sample flow path to a flow rate of the transport fluid flowing through the transport fluid flow path is defined as X, and a viscosity of the sample flowing through the sample flow path measured by a rapid drop viscometer at 25°C is defined as Y (mPa*s), the sample flow path and the transport fluid flow path are configured to satisfy Y≤-6.07X+6.4006 and Y≥2.0.SELECTED DRAWING: Figure 1 【課題】サンプルの粘度が高くても、搬送流体にサンプルの液滴が分散した液滴含有液を安定に製造できる流体取扱装置を提供すること。【解決手段】流体取扱装置は、サンプルを流すためのサンプル流路と、搬送流体を流すための搬送流体流路と、サンプル流路および搬送流体流路に接続され、サンプルを搬送流体で区画してサンプルの液滴が搬送流体中に分散した液滴含有液を生成するための生成部と、生成部に接続され、液滴含有液を流すための液滴流路と、を有する。サンプル流路および搬送流体流路は、搬送流体流路に流す搬送流体の流量に対するサンプル流路に流すサンプルの流量の割合をＸとし、サンプル流路に流すサンプルの２５℃で落急式粘度計にて測定される粘度をＹ（ｍＰａ・ｓ）としたとき、Ｙ≦−６．０７Ｘ＋６．４００６およびＹ≧２．０を満たすように構成されている。【選択図】図１
