PROBLEM TO BE SOLVED: To provide a method for manufacturing an electronic component, which can efficiently manufacture an electronic device, such as very small coil in which conductor wirings are hardly short-circuited each other, without entailing a large amount of time and work. SOLUTION: The method includes the steps of winding or laminating a multilayer film 4 comprising a conductor wiring 2 and an insulating layer 3 so as to form a wound body 5 as a laminate; bonding the layers of the wound body 5; cutting the wound body 5 to be a predetermined thickness; etching a cutting surface of the wound body 5; after etching process, melting the insulating layer 3 which remains on the edge of the cutting surface, and covering the edge of the cutting surface of the electronic component with the insulating layer 3.
