Abstract: A dielectric ceramic composition includes main component grains having a perovskite structure represented by a formula AMO3. “A” includes Ba. “M” includes Ti. D50 of the main component grains is 960 nm or less. D90 of the main component grains is 1460 nm or less.

Abstract: A dielectric ceramic composition includes main component grains having a perovskite structure represented by a formula AMO3. “A” includes Ba. “M” includes Ti. The dielectric ceramic composition includes a 4A subcomponent. The 4A subcomponent includes Fe and Mn. A molar ratio of Mn to a total of Fe and Mn in terms of a metal element is 0.18 to 0.65.

Abstract: The present invention relates to the dielectric composition including barium titanate, strontium titanate, titanium oxide and bismuth oxide. In case when the content of barium titanate, converted to BaTiO3, is a mol %, the content of strontium titanate, converted to SrTiO3, is b mol %, the content of titanium oxide and bismuth oxide, converted to Bi2Ti3O9, is c mol %, and a+b+c=100, a, b and c are values within a scope surrounded by the following four points, i.e. point A, point B, point C and point D in a three-dimensional phase diagram. Point A: (a, b, c)=(52.1, 40.0, 7.9); point B: (a, b, c)=(86.5, 5.6, 7.9); point C: (a, b, c)=(91.0, 5.6, 3.4); point D: (a, b, c)=(56.6, 40.0, 3.4).

Abstract: A design bar code 100 according to one particular embodiment includes a bar symbol sequence 110 that contains a plurality of bar symbols aligned in a scanning direction X with spaces therebetween, and an additional pattern 130 that supplements a pattern represented by the outer shape of the bar symbol sequence 110. The length of one or more bar symbols in a direction Y is defined so as to have a contour forming at least a portion of a rendered pattern. The additional pattern 130 may positioned as necessary in the region outside of the belt area 112 so as to supplement the pattern represented by the outer shape of the bar symbol sequence 110.
