A method for forming a thick film pattern is provided which can easily perform pattern formation even when a photosensitive paste containing a powdered conductor at a high content and having a low optical transmittance is used and which can form a thick film pattern having a rectangular cross-section and superior high-frequency transmission characteristics. In addition, a photosensitive paste used therefor is also provided. The thick film pattern having a predetermined shape can be formed by the steps of determining the photocurable depth d of a photosensitive paste; coating with the photosensitive paste in consideration of the photocurable depth d so as to form a photosensitive paste film having a predetermined thickness t; exposing the photosensitive paste film; and developing the exposed photosensitive paste film. Preferably, the coating with the photosensitive paste is performed so that the relationship between the photocurable depth d of the photosensitive paste and the thickness t of the photosensitive paste film satisfies the equation t≦d.
A method for forming a thick film pattern, comprising
A substrate having a cured thick film photosensitive paste pattern thereon, wherein the photosensitive paste comprises at least one inorganic substance and in which the inorganic material having the largest concentration has an average particle diameter m and the paste has a photocured depth d and the pattern has a thickness t which is about equal to or less than said photocured depth d of the photosensitive paste plus the diameter m.
