Abstract

A flex-rigid wiring board has an insulative adhesive interposed between portions, lapping over each other, of the rigid and flexible substrates; and the interconnecting electrode pads on the rigid and flexible substrates are electrically connected to each other through a conductor lump penetrating the insulative adhesive, thereby providing lowered inductance in the high-frequency band, shortened signal-delay time, reduced noise generation due to signal reflected-wave, reduced drop impact, high connection reliability and high freedom of wire connection, and the wiring board can advantageously be manufactured with a reduced cost and a high yield.
