A vehicle lamp includes a semiconductor laser element configured to emit laser light, a condenser lens configured to condense the laser light, a phosphor configured to form white light by converting wavelength of at least a portion of the laser light condensed, and a reflector configured to reflect the white light. A light transmitting portion is formed in a portion, at which an extension path obtaining by extending an optical path of the laser light before contacting the phosphor is intersected with the reflector, of the reflector. A light confinement part is formed above the light transmitting portion.
