Patent ID: 7470333

Claim:
A non-oriented electrical steel sheet, comprising: a particular number density of inclusions with an equivalent volume diameter of less than 100 nm contained in the steel sheet, the particular number density of inclusions being approximately at most 1×10 10 [/mm 3 ]; and comprising, by mass %: C: up to 0.01%, Si: 0.1% to 7.0%, Al: 0.1% to 3.0%, Mn: 0.1% to 2.0%, REM: 0.0003% to 0.05%, Ti: up to 0.02%, S: up to 0.005%, N: up to 0.005%, and a balance of Fe and inevitable impurities, and wherein the mass % of Al, the mass % of N and the mass % of Ti satisfy the following equation: log([Ti]×[N])−1.19×log([Al]×[N])+1.84>0.
