Yes. The evidence for this is the presence of magma at, and below, the surface of the earth. The core is estimated to be as hot as 7000 Celsius. This heat is thought to be produced by radioactive decay of elements like uranium. Eventually the core will cool.
Interestingly, the molten metallic outer core revolving around the solid inner core is thought to produce the protective magnetic field around Earth. The cooling of the core will probably have the effect of collapsing Earth's magnetic field, leaving Earth unprotected from solar radiation. This radiation will likely sterilize the earth of most life as we know it. Cockroaches may be one of the exceptions, as lethal doses of radiation for them are 6 -15 times higher than for humans.

What is the distance of the inner core?
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
What is hotter inner mantle or outer mantle?
Oh, dude, the inner mantle is definitely hotter than the outer mantle. Like, we're talking about temperatures reaching up to 4000°C in the inner mantle compared to a measly 500-900°C in the outer mantle. So, if you're looking for a hot spot, the inner mantle is where it's at.
Is the inner part of the earths crust hot melted rock?
No, the inner part of the Earth's crust is not hot melted rock. The inner core of the Earth is made up of solid iron and nickel, while the outer core is composed of liquid iron and nickel. The hot melted rock is found in the mantle layer beneath the crust.
