The present invention relates to a photosensitive ceramic composite and a
method for manufacturing a multilayer substrate using the composite. The
photosensitive ceramic composite and manufacturing method of the present
invention are applicable to circuit members and components for ceramic
multilayer substrates for high-frequency wireless communication. The
photosensitive ceramic composite contain inorganic particles and a photo
sensitive organic components. The inorganic particles have at least
surface sections containing an inorganic material having a refractive
index less than that of inner sections of the inorganic particles.
