PROBLEM TO BE SOLVED: To provide an ink for deposition which allows for highly accurate inspection (discharge inspection) of a droplet discharge head, even if the ink for deposition is not colored with high density or the wetting and spreading for a discharged object is high, and to provide a discharge inspection method and a discharge inspection device, and a method of manufacturing a light-emitting element using such an ink for deposition, a light-emitting element, a light-emitting device and an electronic apparatus.SOLUTION: An ink for deposition contains a material composing a hole transport layer or a hole injection layer included in an organic electroluminescent element or a deposition material that is a precursor thereof, and a liquid medium for dispersing or dissolving the deposition material. An index material, emitting light when irradiated with excitation light, is added to the deposition material. 【課題】成膜用インクが高濃度に着色されていなかったり吐出対象物に対する濡れ拡がり性が高かったりしても、液滴吐出ヘッドの検査（吐出検査）を高精度に行うことができる成膜用インク、吐出検査方法および吐出検査装置を提供すること、また、かかる成膜用インクを用いた発光素子の製造方法、発光素子、発光装置および電子機器を提供すること。【解決手段】本発明の成膜用インクは、有機エレクトロルミネッセンス素子に含まれる正孔輸送層または正孔注入層を構成する材料またはその前駆体である成膜材料と、成膜材料を分散または溶解させる液性媒体と、を含み、成膜材料には、励起光が照射されることにより発光する指標材料が添加されている。【選択図】なし
