摘要：
An insulating thick film composition for forming a solder resist layer having a high degree of positional accuracy is provided, which can suppress warping and undulation of a multilayer ceramic substrate and can maintain the superior electrical characteristics thereof. The insulating thick film composition is primarily composed of a powdered ceramic having the same composition system as that of a powdered ceramic contained in a green ceramic sheet, and the mean particle diameter of the powdered ceramic of the insulating thick film composition is smaller than that of the powdered ceramic contained in the green ceramic body.
