Abstract
A wired circuit board includes a metal supporting layer, an insulating base layer and a conductor layer from bottom to top. A peripheral edge of the insulating base layer includes an extension part extending further outward relative to the metal supporting layer. The metal supporting layer has a thickness T1 of 50 μm or more.
Claims11
A wired circuit board comprising:
- a metal supporting layer;
- an insulating base layer;
- and
- a conductor layer from bottom to top,
- wherein a peripheral edge of the insulating base layer includes an extension part extending further outward relative to the metal supporting layer,
- wherein the metal supporting layer has a thickness of 50 μm or more, and
- wherein the extension part has an extension length of 5 μm or more and 100 μm or less.
