<P>PROBLEM TO BE SOLVED: To provide a flashlamp capable of suppressing the generation of fluctuation of arc discharge. <P>SOLUTION: In a flashlamp 1, a tip end part 62 of a negative electrode 60 and a tip end part 72 of a positive electrode 70 oppose to each other on a reference line RL. A tip end part 82 of a trigger electrode 80 is positioned on one side and a tip end part 92 of a trigger electrode 90 is positioned on the other side with respect to a reference plane RS including the reference line RL. A terminal 82a of the tip end part 82 of the trigger electrode 80 and a terminal 92a of the tip end part 92 of the trigger electrode 90 are separated from the reference line RL, and the tip end parts 82 and 92 are formed so as to taper off toward the reference line RL. Therefore, arc discharge is generated in a limited R which is a path from a terminal portion of the tip end part 62 of the negative electrode 60 to a terminal portion of the tip end part 72 of the positive electrode 70 through the terminal portion of the tip end part 82 of the trigger electrode 80 and the terminal portion of the tip end part 92 of the trigger electrode 90. <P>COPYRIGHT: (C)2012,JPO&INPIT |
