Ultraviolet lamp

The utility model relates to an ultraviolet lamp which comprises a transparent tube body, a first electrode and a second electrode, one section of the first electrode extends into the tube body and does not exceed the tube body, two ends of the tube body are flattened through hot melting to form a first flattened part and a second flattened part, and a sealed air storage cavity is formed in the middle of the tube body. The gas storage cavity is filled with working gas; the section, extending into the tube body, of the first electrode is fixed by the first flattening part and the second flattening part; the other section of the first electrode is a terminal outside the tube body; the flattening part close to the wiring end of the first electrode is a second flattening part, and the flattening part far away from the wiring end of the first electrode is a first flattening part; the first electrode is bent at a part in the first flattened part; and the second electrode is a metal net sleeved on the outer wall sur
