PROBLEM TO BE SOLVED: To provide an illumination device capable of suppressing decrease in a light emission volume even when a voltage is reduced, and a vehicular lighting fixture.SOLUTION: An illumination device according to an embodiment comprises: a substrate; a light emitter provided on the substrate; and a resistor connected to the light emitter in series. A voltage ratio of the resistor when a half of a first voltage is applied to a first circuit where the light emitter and the resistor are connected to each other in series is equal to 25% or less than a voltage ratio of the resistor when the first voltage is applied to the first circuit. A voltage ratio of the resistor of a second circuit, where the light emitter and the resistor are connected to each other in series, when the half of the first voltage is applied to the second circuit is higher than the voltage ratio of the resistor of the first circuit when the half of the first voltage is applied to the first circuit.SELECTED DRAWING: Figure 4 |
