ALUMINA SUBSTRATE AND RESISTOR USING SAME

An alumina substrate according to the present disclosure has a pore on a surface thereof and is composed of an alumina-based ceramic that contains 96% by mass or more of Al as a value of an Al2O3equivalent among 100% by mass of all constituent components thereof. Furthermore, a surface area occupanc...

description	An alumina substrate according to the present disclosure has a pore on a surface thereof and is composed of an alumina-based ceramic that contains 96% by mass or more of Al as a value of an Al2O3equivalent among 100% by mass of all constituent components thereof. Furthermore, a surface area occupancy of the pore is 1.5% or greater and 6.0% or less. Furthermore, an average value D of an equivalent circle diameter of the pore is 0.9 µm or greater and 2.0 µm or less. Then, a standard deviation Dσ of an equivalent circle diameter of the pore is 1.0 µm or less.
