Sterilizing apparatus

A sterilizing apparatus that radiates light including ultraviolet rays onto a target object, characterized by

• emitting first wavelength light having a peak wavelength in a wavelength range of 190 nm or more and 230 nm or less, and
• second wavelength light having a peak wavelength in a wavelength range of 400 nm or more and 460 nm or less,
• being provided with:
• a laser light source that oscillates the second wavelength light;
• and
• a frequency conversion element that receives the second wavelength light oscillated from the laser light source, and converts a portion of the second wavelength light into the first wavelength light,
• the frequency conversion element emitting the first wavelength light and the second wavelength light that has not been converted into the first wavelength light,
• light intensity of the ultraviolet rays of a wavelength range of more than 230 nm and less than 400 nm radiated onto the target object being less than 3 mW/cm2, and
• the target object including a somatic cell of a patient.
