Abstract
First inner gas holesand first outer gas holesof a gas sensor are formed so that the following conditions are satisfied: a first-inner-hole count Nin≧3, 0<an inner/outer hole count ratio Nr≦0.5, and 0<an inner/outer hole-area ratio Ar≦0.25, where the first-inner-hole count Nin represents the number of first inner gas holes, a first-inner-hole average area Ain [mm] represents (the total opening area of the first inner gas holes)/(the first-inner-hole count Nin), a first-outer-hole count Nout represents the number of the first outer gas holes, a first-outer-hole average area Aout represents (the total opening area of the first outer gas holes)/(the first-outer-hole count Nout), the inner/outer hole count ratio Nr represents the first-inner-hole count Nin/the first-outer-hole count Nout, and the inner/outer hole-area ratio Ar represents the first-inner-hole average area Ain/the first-outer-hole average area Aout.
