Electronic Device

摘要

The present invention provides a miniaturised electronic device (10A) that is capable of high reliability. To this end, the electronic device (10A) has an electronic circuit (12), comprising: a substrate (11) with a circuit formation surface (11a) on which one part of the electronic circuit (12) is formed; a polymide layer (15) that is formed on the circuit formation surface (11a); and a spiral inductor (20) constituting another part of the electronic circuit (12), which is formed into a pattern on the polymide layer (15).
