PROBLEM TO BE SOLVED: To provide a translucent member with a hydrophilic film which allows for speedy water film formation even at an initial step of moisture attachment and therefore has higher hydrophilic property than conventional ones, a method of manufacturing the translucent member with the hydrophilic film and an onboard camera having the translucent member with the hydrophilic film.SOLUTION: The translucent member with a hydrophilic film related to the present invention is the translucent member with the hydrophilic film having a hydrophilic film formed on a surface of a translucent substrate, the hydrophilic film has amorphous silica as a base phase, a hydroxyalkylene amino group binds to a surface area of the base phase via an organic chain X and the organic chain X is an alkylene chain or an alkyleneoxyalkylene chain.SELECTED DRAWING: Figure 1 【課題】水分付着の初期段階であっても速やかな水膜形成を可能にするため、従来よりも高い親水性を有する親水膜付き透光部材、該親水膜付き透光部材の製造方法、および該親水膜付き透光部材を具備する車載カメラを提供する。【解決手段】本発明に係る親水膜付き透光部材は、透光基材の表面に親水膜が形成された親水膜付き透光部材であって、前記親水膜は、非晶質シリカを母相とし、前記母相の表面領域にヒドロキシアルキレンアミノ基が有機鎖Ｘを介して結合しており、前記有機鎖Ｘは、アルキレン鎖またはアルキレンオキシアルキレン鎖であることを特徴とする。【選択図】図１
