Abstract
A flat coil, a manufacturing method thereof and an electronic apparatus are disclosed. The manufacturing method comprises: rolling a metal foil lamination onto a carrier roller to form a foil rod, wherein the metal foil lamination includes at least one layer of metal foil; sliding the foil rod from the carrier roller; slicing the foil rod into thin disks; and processing the thin disks to form at least one flat coil, wherein a pressing roller is pressed against the carrier roller via the metal foil lamination with a controlled pressing force as the metal foil lamination is rolled.
