Abstract
An object of the present invention is to provide magnesium oxide particles that have a high heat conductivity and excellent properties as heat-dissipating filler, and can prevent problems such as soft errors in the memory. The magnesium oxide particles have a BET specific surface area of 0.1 to 17 m/g, and an α dose of 0.005 c/cm·Hr or lower, the particles exhibiting a relation between an X-ray diffraction peak intensity y (cps) at a Bragg angle (2θ) of 42.80° to 43.00° and the BET specific surface area x (m/g) as represented by the following inequality (1):960+33000  (1).
