1. An organic substance decomposition catalyst used for decomposing an organic substance, the organic substance decomposition catalyst comprising:
a perovskite-type complex oxide denoted by a formula AxByMzOw in which
A includes Ba,
B includes Zr,
M represents Mn and Co,
a composition ratio of Mn to Co is represented by Mn:Co=z1:z2,
z=z1+z2,
y+z=1.000,
0.100<z1+z2≤0.200,
0.00<z1/(z1+z2)<0.75,
w represents a positive value satisfying electrical neutrality,
1.000≤x/(y+z)≤1.050,
the organic substance decomposition catalyst has a specific surface area of 7.2 m2/g or more, and
an integral width of the peak intensity of a (222) face of the organic substance decomposition catalyst in X-ray diffraction measurement is in a range of 0.622° or more.
