Abstract
A photosensitive ceramic green sheet having an inorganic powder including 30% or more of a glass powder and a photosensitive organic component as essential components, characterized by satisfying -0.05.ltoreq.N2-N1.ltoreq.0.1 where N1 is the average refractive index of the organic component and N2 is the average refractive index of the inorganic powder is used to provide a highly accurate ceramic package with a high aspect ratio.
