Abstract
A circuit unit is provided in which it is possible to connect circuit board to a terminal using a simple operation without removing a passivation film from above the terminal. A metal electrode which conducts with a circuit element is formed above a substrate. Multiple column shaped insulation films are each formed at a uniform pitch in two intersecting directions above the surface of the metal electrode. A metal electrode is formed above the metal electrode including the insulation film. A passivation film is formed on a surface of the metal electrode. Conductive beads are stuck between pairs of projection structured bodies formed on a surface of the passivation film, the passivation film on a side surface of the projection structure is scraped whereby the conductive beads conduct simultaneously with the metal electrode and an electrode formed on the circuit board.
