The general formula is represented by (Ba 1 -α M α) A (Ti 1 -β Mn β) B O 3 and the crystal structure is a hexagonal crystal, an effective ionic radius at the time 12 when the coordination number of M 12 coordinated Ba 2 + Hexagonal barium titanate that is within ± 20% of the effective ion radius and A, B, α, and β satisfy the relationship of 1.000 <(A / B) ≤1.040, 0≤α <0.003, 0.03≤β≤0.2 as a sub-component as a main component, and for this main component as 100 mol, the alkaline earth oxide of the MgO or the like, the Mn 3 O 4 and / or Cr 2 O 3, and CuO and Al 2 O 3 and a rare earth element oxide, SiO 2 Provided is a dielectric ceramic composition comprising a specific amount of a glass component to contain. According to the present invention, it is possible to provide a hexagonal barium titanate powder and a dielectric ceramic composition which are relatively suitable for producing a dielectric layer of an electronic component having a relatively high dielectric constant, excellent insulation resistance, and ensuring sufficient reliability. |
