SILICON NITRIDE SINTERED COMPACT AND HEAT CONDUCTION MEMBER
[Object] To provide a silicon nitride sintered body and a heat conduction member which have high corrosion resistance to an alkali component and high thermal conductivity. [Solution] The silicon nitride sintered body includes a silicon nitride crystal, and a grain boundary phase including at least any of sodium oxide and potassium oxide. A total amount of the sodium oxide and the potassium oxide is 0.2% by mass or more and 1% by mass or less in terms of Na 2 O and K 2 O on the basis of the total mass. When this configuration is satisfied, it is possible to attain both high corrosion resistance to alkali and high heat conductivity.
