Abstract

A high yield ratio type high strength steel sheet contains as component composition, by % by mass, 0.03% to 0.20% C, 1.0% or less Si, more than 1.5% to 3.0% Mn, 0.10% or less P, 0.05% or less S, 0.10% or less Al, 0.010% or less N, one or more kinds of elements selected from among Ti, Nb, and V whose total content is in the range from 0.010% to 1.000%, and the balance Fe with inevitable impurities, and a structure containing ferrite and a second phase as a microstructure. The ferrite has an area ratio of 50% or more and an average crystal grain size of 18 ?m or less. The second phase contains martensite whose area ratio is in the range from 1% to less than 7%. The thickness of a bandlike structure formed by the second phase satisfies a predetermined relational expression.
