About 760miles thick.
1220 km thick
The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.

The distance from the boundary between the mantle and the outer core, to the center of the Earth, is around 3,470 km, or 2,156 miles.
the thickness of each part is the mantle, the inner core, and inner core
It is 1300km and consists of mainly iron and nickel.
The inner core of the Earth is approximately 1,200 kilometers (745 miles) thick. It is a solid metal sphere primarily composed of iron and nickel at extreme temperatures and pressures. The inner core is surrounded by the liquid outer core.
The smallest part of the Earth is its core, which is made up of a solid inner core and a liquid outer core. The inner core is about 1,500 miles (2,400 kilometers) in diameter, while the outer core is larger, extending to about 1,400 miles (2,200 kilometers) in thickness.
about 1,200 km
in the outer core it has a 6960 km.While the inner core is about 2440 km. in diameter
The upper core of Earth, also known as the outer core, has a thickness of approximately 2,200 kilometers. It is a layer of molten iron and nickel that surrounds the solid inner core.
