A vehicle lamp including a light source, a glass disposed in front of the light source, a housing supporting the light source and the glass, and a thermoelectric element unit generating cold wind and hot wind. The thermoelectric element unit includes a first part connected to the first flow path and generating one of cold air and hot air, a second part connected to the second flow path and generating the other one of the cold air and the hot air, a body accommodating the first part and the second part and having an opening formed on an upper surface, and a fan configured to be disposed on the opening of the body and introduce the air in a direction from the upper surface to a lower surface of the body. The thermoelectric element unit is positioned on an upper end of an external rear surface of the housing.

A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.
