To provide a vehicular interior lighting device which improves a degree of freedom in design.SOLUTION: A vehicular interior lighting device 1 includes: a light source 20; a bus bar 14 which has a plate-like electrode section 14a; a lens 13 which has a light transmission section 13a and a holding structure section 13b; conductive films 30 which are formed in a part of the lens 13; and a control section 22 which switches on/off of the light source 20 according to a change of electrostatic capacitance between a finger tip F touching a light irradiation surface 13c and the electrode section 14a. The holding structure section 13b has a first side wall section 13f as a wall section with which a second main plane 14d of the electrode 14a is brought into contact and is positioned outside a light receiving surface 13d in an irradiation direction view of light. The conductive films 30 are formed on the light receiving surface 13d and a first outer wall surface 13h on an opposite side of a first inner wall surface 13i as a surface with which the second main plane 14d of the electrode section 14a is brought into contact in the first side wall section 13f. The conductive film 30 formed on the light receiving surface 13d and the conductive film 30 formed on the first outer wall surface 13h are continued to each other.SELECTED DRAWING: Figure 6

    【課題】デザインの自由度を向上させる車室内照明装置を提供する。【解決手段】車室内照明装置1は、光源20と、平板状の電極部14aを有するバスバー14と、光透過部13aと保持構造部13bとを有するレンズ13と、レンズ13の一部に形成される導電膜30と、光照射面13cを触れた指先Fと電極部14aとの間の静電容量の変化に応じて光源20のオン/オフを切り替える制御部22とを備える。保持構造部13bは、電極部14aの第2主平面14dを接触させる壁部としての第1側壁部13fを有し、かつ、光の照射方向視で受光面13dの外側に位置する。導電膜30は、受光面13dと、第1側壁部13fにおいて電極部14aの第2主平面14dが接触する面としての第1内壁面13iとは反対側の第1外壁面13hとに形成される。受光面13dに形成される導電膜30と、第1外壁面13hに形成される導電膜30とは、互いに連続する。【選択図】図6
