To provide a lighting fixture unit which can change the setting of a light flux acquired by a simple structure even when an LED chip and an LDM are commonalized, and to provide a vehicular lighting fixture.SOLUTION: A lighting fixture unit includes: a light emitting part in which a plurality of light emitting elements are connected in series by wiring between light emitting elements; and a wiring board in which a wiring pattern (45) is formed. In a first light emitting element (42a) connected closest to an anode side, one out of a first anode electrode (46a), a first intermediate electrode (46b) and a first cathode electrode (46c) is electrically connected to the wiring pattern (45) other than the wiring between light emitting elements alternatively, and in a second light emitting element (42b) connected closest to a cathode side, one out of a second cathode electrode (46c), a second intermediate electrode (46b) and a second anode electrode (46a) is electrically connected to the wiring pattern (45) other than the wiring between light emitting elements alternatively.SELECTED DRAWING: Figure 4 【課題】ＬＥＤチップとＬＤＭを共通化しても、簡便な構成によって得られる光束の設定を変更することが可能な灯具ユニットおよび車両用灯具を提供する。【解決手段】複数の発光素子が発光素子間配線によって直列接続された発光部と、配線パターン（４５）が形成された配線基板を備え、最もアノード側に接続された第１発光素子（４２ａ）は、第１アノード電極（４６ａ）、第１中間電極（４６ｂ）または第１カソード電極（４６ｃ）の何れか一つが、択一的に前記発光素子間配線以外の配線パターン（４５）と電気的に接続され、最もカソード側に接続された第２発光素子（４２ｂ）は、第２カソード電極（４６ｃ）、第２中間電極（４６ｂ）または第２アノード電極（４６ａ）の何れか一つが、択一的に前記発光素子間配線以外の配線パターン（４５）と電気的に接続されている灯具ユニット。【選択図】図４
