Abstract
Disclosed are a method for manufacturing a coil, a coil, and an electronic device. The method includes: bonding a first side of a metal sheet onto a laser-transmitting substrate by an adhesive layer; cutting a coil pattern on a second side of the metal sheet by the laser to form a coil running through the two sides of the metal sheet on the metal sheet; bonding the second side of the metal sheet onto an adhesive tape; transmitting the laser through the laser-transmitting substrate to act on the adhesive layer to detach the laser-transmitting substrate and the adhesive layer from the first side of the metal sheet; exposing the coil pattern on the first side of the metal sheet; and forming an encapsulation layer on the coil to encapsulate the first side of the coil.
