PURPOSE:To restrain the printing defect of a conductor paste due to the precipitation of a boric acid crystal and to restrain a void from being produced in a laminated body when a multilayer wiring board is manufactured by using borosilicate glass. CONSTITUTION:When a green sheet to manufacture a multilayer wiring board is formed, a base is added, and the precipitation of a crystal is suppressed by a neutralization reaction with boric acid. Thereby, it is possible to obtain the multilayer wiring board which does not contain any void between layers and which is uniform and dense. |
