PROBLEM TO BE SOLVED: To provide a mouthpiece of illumination light source capable of improving dielectric strength while ensuring attaching/detaching property.SOLUTION: A mouthpiece 20 of an illumination light source includes: two pin embedded parts 22 in which two pins from the illumination light source are embedded in an end face 25; and two pin end parts 23 provided to the front end of the two pin embedded parts 22. The two pin embedded parts 22 are arranged so that the front end parts have a distance larger than the distance on the end face 25. Each of the two pin end parts 23 is arranged so as to have a cross-sectional area along the end face 25 larger than the cross-sectional area along the end face 25 of the pin embedded part 22. Each of the two pin end parts 23 is also arranged so that the distance therebetween gets larger as being far away from the end face 25. |
