PROBLEM TO BE SOLVED: To widely change intensity of light generated by a light generation apparatus. SOLUTION: This light generation apparatus includes an X-ray source 10, a high-voltage generation circuit 20, a CPU 40 and the like. The generation circuit 20 has a plurality of capacitors C1-C3 and a plurality of switches S1-S6 arranged in charge paths and discharge paths of the capacitors. The capacitors for supplying electric energy to the X-ray source 10 are changed over by controlling the switches by the CPU 40, and thereby the electric energy supplied to the X-ray source 10 is changed.
