Abstract: A vehicle lamp includes a light guide plate including a plurality of light-exiting portions and a low-luminance portion, which is located between adjacent light-exiting portions and outputs light having luminance lower than luminance of light exiting from the light-exiting portion; a plurality of light sources each emit light having a light emission peak wavelength in a range from 420 nm to 550 nm to enter the light guide plate; and a wavelength conversion member that is disposed on the plurality of light-exiting portions and emits light having a light emission peak wavelength in a range from 540 nm to 700 nm by converting a wavelength of the light exiting from the light-exiting portion.
