    摘要: A lamp device and a projector having the lamp device eliminated of light leaking in a direction opposite to a reflecting direction at a rear end of an encapsulation fixing an arc tube on a reflection mirror is simply and inexpensively provided. An arc tube and a reflection mirror are provided. The arc tube has encapsulations one of which is inserted in a cylinder of the reflection mirror thereby securing the encapsulation and the cylinder together by an adhesive. The bulb of the arc tube and the other encapsulation are positioned on a side close to a reflection surface of the reflection mirror. The encapsulation inserted in the cylinder and positioned on a side opposite to the reflection surface has an end at least at an end face of which is covered with the adhesive thereby providing light shield.
