To provide a lighting fixture 10 for a vehicle suppressing the change of amount of light of a semiconductor light emitting element 32 caused by temperature change in the semiconductor light emitting element 32.

The lighting fixture 10 used for the vehicle is equipped with the semiconductor light emitting element 32 generating light, a time measurement part 42 measuring the time when the semiconductor light emitting element 32 continuously generating the light, and an electric current supply part 44 supplying supply electric current increasing according to the time measured with the measurement part 42 to the semiconductor light emitting element 32. The time measurement part 42 has a capacitor 114 charged with the time constant approximately equal to the time constant with which the temperature of the semiconductor light emitting element 32 rising when the semiconductor light emitting element 32 generates the light, and the electric current supply part 44 outputs the supply electric current increasing according to the time measured with the time measurement part 42 by outputting the supply electric current increasing according to the rise of the charged voltage charged in the capacitor 114.
