Abstract
A metal nitride material for a thermistor consists of a metal nitride represented by the general formula: M(AlSi)(NO)(where 'M' represents at least one of Ti, V, Cr, Mn, Fe, and Co, 0.0<v<0.3, 0.70≤y/(x+y)≤0.98, 0.45≤z≤0.55, 0<w≤0.35, and x+y+z=1), wherein the crystal structure thereof is a hexagonal wurtzite-type single phase. A method for producing the metal nitride material for a thermistor includes a deposition step of performing film deposition by reactive sputtering in a nitrogen and oxygen-containing atmosphere using an M-Al—Si alloy sputtering target (where 'M' represents at least one of Ti, V, Cr, Mn, Fe, and Co).
