摘要

A printed-wiring board capable of preventing occurrence of short-circuit is provided. A printed-wiring board (100) comprises a via land (2A), a glass epoxy resin layer (3), a via conductor (6), and a block layer (4A). The via land (2A) is formed on a core layer (1). The glass epoxy resin layer (3) is formed on the core layer (1) and via land (2A). The via conductor (6) is formed on the via land (2A). The block layer (4A) is formed on the via land (2A) and between the via conductor (6) and glass epoxy resin layer (3).
