Abstract:
To provide an electronic component having printing, which can achieve both of a moisture resistance capability and visibility of printing, and a method of manufacturing the same. A method of manufacturing an electronic component having printing, including preparing an electronic component before being subjected to printing, which is provided with a magnetic element body made of an alloy magnetic material containing a transition metal on a surface thereof, and a glass layer that contains Bi with which the magnetic element body is at least partly coated and does not contain a transition metal, and irradiating the electronic component before being subjected to printing with laser light having a wavelength of 1064 nm so that the laser light is transmitted through the glass layer, so that a printing portion is formed at a partial glass portion in a vicinity of an interface between the magnetic element body and the glass layer.
