<p>A lamp device includes a mirror reflector (10) having a cylindrical, hollow lamp mounting portion (113) at a rear end portion of a reflector body (11) having a curved surface, a lamp (20) housed in the mirror reflector and having an end with a sealing portion (22) which is inserted into the lamp mounting portion (113), and an adhesive (30), filled between the outer surface of the sealing portion (22) and the inner surface of the lamp mounting portion (113) while the lamp sealing portion (22) is inserted into the lamp mounting portion (113) of the reflector body (11), for bonding the mirror reflector (10) to the lamp (20). A space region (40) is formed inside the lamp mounting portion (113) and is surrounded by the inner surface of the lamp mounting portion (113), the outer surface of the sealing portion (22), and the adhesive (30) filled therebetween. The end of the space region on the side of the curved surface is open, and the space region (40) prevents heat conduction between the lamp mounting portion (113) and the sealing portion (22).</p> |
