To provide a vehicular lighting device which can suppress the current flowing in a light-emitting element and suppress the sudden fluctuation of the entire light flux even when the voltage applied to the vehicular lighting device is increased, and provide a vehicular lighting fixture.SOLUTION: A vehicular lighting device related to an embodiment includes: a socket; and a light-emitting module provided on one end side of the socket. The light-emitting module includes: a substrate having a wiring pattern; a plurality of light-emitting elements which is electrically connected to a first pad of the wiring pattern respectively, and connected in series; and a plurality of thermistors which is electrically connected to a second pad of the wiring pattern respectively and connected in parallel. The shortest distance between the first pad and the second pad is larger than the thickness of the substrate.SELECTED DRAWING: Figure 5 【課題】車両用照明装置に印加される電圧が増加した場合であっても、発光素子に流れる電流を抑制することができ、且つ、全光束の急激な変動を抑制することができる車両用照明装置、および車両用灯具を提供することである。【解決手段】実施形態に係る車両用照明装置は、ソケットと；前記ソケットの一方の端部側に設けられた発光モジュールと；を具備している。前記発光モジュールは、配線パターンを有する基板と；それぞれが前記配線パターンの第１のパッドと電気的に接続され、直列接続された複数の発光素子と；それぞれが前記配線パターンの第２のパッドと電気的に接続され、並列接続された複数のサーミスタと；を有する。前記第１のパッドと、前記第２のパッドとの間の最短距離は、前記基板の厚みよりも大きい。【選択図】図５
