PROBLEM TO BE SOLVED: To provide a liquid drop auxiliary device capable of preventing scattering of the liquid caused by foaming or the like.SOLUTION: A resin substrate 50 functioning as a liquid drop auxiliary device has a film 52 pasted on a surface (lower surface) having a contact with a circular disk for collecting blood and on a surface (upper surface) on the opposite side, and when a discharge part (nozzle) breaks the film 52 and sends the blood up to a hole inlet (flow path entrance of the circular disk) through an open hole 51 so as to be dropped, the blood which is foamed and cannot be dropped into the hole inlet (flow path entrance) enters again the hole inlet without leaking to the outside through the film 52. As a result, scattering of the blood caused by foaming or the like can be prevented. 【課題】発泡などによる液体の飛散を防止することができる液体滴下補助装置を提供することを目的とする。【解決手段】液体滴下補助装置として機能する樹脂基板５０には、血液を採取する円板と接する面（下面）と反対側の面（上面）にフィルム５２を貼りつけて備えており、吐出部（ノズル）がフィルム５２を破って貫通孔５１を介して穴の入口（円板の流路入口）にまで血液を滴下する際に発泡して穴の入口（流路入口）に滴下できなかった血液もフィルム５２により外に漏れ出ることなく穴の入口に再度入っていく。その結果、発泡などによる血液の飛散を防止することができる。【選択図】図３
