Provided are an electronic component manufacturing method by which even a platable layer made of a difficult-to-plate material can be easily plated with good adhesion without using a special chemical solution or a photolithography technique, and an electronic component which has a peel strength of 0.1 N/mm or greater as measured by a copper foil peel test. A picosecond laser beam having a pulse duration on the order of a picosecond or a femtosecond laser beam having a pulse duration on the order of a femtosecond is emitted at a surface of a platable layer (2) in order to roughen the surface, a wiring pattern is formed using a mask (13), and a plated part (12) is formed on the surface of the wiring pattern.
