metal hydride (A);

metal powder (B) that is one or more selected from the group consisting of tungsten powder, molybdenum powder, aluminum powder, titanium powder, and magnesium powder; and

perchlorate (C).

2. The ignition powder composition for igniter according to claim 1, wherein the metal hydride (A) contains zirconium hydride and/or titanium hydride.

3. The ignition powder composition for igniter according to claim 1, wherein the metal powder (B) contains tungsten powder.

4. The ignition powder composition for igniter according to claim 1, wherein the content of the metal hydride (A) is 10 mass % to 50 mass %.

5. The ignition powder composition for igniter according to claim 1, wherein:

the content of the metal hydride (A) is 10 mass % to 50 mass %,

the content of the metal powder (B) is 10 mass % to 50 mass %, and

the content of the perchlorate (C) is 20 mass % to 70 mass %.

6. An igniter using the ignition powder composition for igniter according to claim 1.

7. A gas generator for seat belt pretensioner, using the igniter according to claim 6.
