Printed circuit board, method of producing the same, and electronic unit

摘要

A printed circuit board is disclosed that is able to prevent outflow of a potting resin out of a sealing region. The printed circuit board includes a conductive pattern formed on an insulating substrate, an electrode for connecting an electronic part to the conductive pattern, and a stripe-like resin-outflow-prevention dam arranged in a periphery of a resin-sealing region covering the electronic part. An outer side surface and an upper surface of the resin-outflow-prevention dam subtend an acute angle.
