The invention relates to a self-triggering type metal halide lamp which comprises a glass shell, a conducting supporting frame arranged in the glass shell, a getter, a metal halide lamp voltaic arc tube, a core pillar and a lamp cap connected at the lower end of the glass shell. The metal halide lamp voltaic arc tube is supported on the core pillar through the conducting supporting frame. A starter is arranged in the glass shell and comprises two starting resistors and two metal take-off devices. A main electrode of one end of the metal halide lamp voltaic arc tube is electrically connected with a first pin of the core pillar through a first flying wire, an auxiliary electrode of the end is sequentially connected with the first starting resistor, the first metal take-off device and a second pin of the core pillar in series through a second flying wire and a main electrode of other end of the metal halide lamp voltaic arc tube is electrically connected with the second pin of the core pillar through a wire. An auxiliary electrode of the other end of the metal halide lamp voltaic arc tube is sequentially connected with the second starting resistor, the second metal take-off device and a first pin of the core pillar through a wire. The self-triggering type metal halide lamp has the self-triggering function, does not need an externally-arranged electronic triggering device to be turned on, and is convenient to install, safe and reliable.
