At least a part of light outputted from a light source (9) passes through a projection lens (7). A lens holder that holds the projection lens (7) is formed of a first material having a first heat conductivity. A heat conducting plate (20) is formed of a second material having a second heat conductivity that is higher than the first heat conductivity, and is disposed in contact with a lower side supporting section (6c) of the lens holder (6). L'invention concerne au moins une partie de lumière émise par une source de lumière (9), qui passe à travers une lentille de projection (7). Une porte-lentille, qui porte la lentille de projection (7), est formé d'un premier matériau ayant une première conductivité thermique. Une plaque à conduction thermique (20) est formée d'un second matériau ayant une seconde conductivité thermique, qui est supérieure à la première conductivité thermique, et est disposée en contact avec une section de support latéral inférieur (6c) de la porte-lentille (6).
