发明名称 FORMING METHOD OF OUTER ELECTRODE OF ELECTRONIC COMPONENT
摘要 PROBLEM TO BE SOLVED: To enable outer electrodes fine in shape to be formed at a narrow pitch by a method, wherein an outer electrode conductor film is formed on the surface of a component, and the disused part of the conductor film is removed, whereby outer electrodes prescribed in shape are formed. SOLUTION: Four discrete circuits each composed of one or more elements selected out of a coil, a capacitor, a resistor and the like are jointly provided separating from each other by a space in a longer direction inside a component main body 1, and the ends 2 of the discrete circuits are led out to the two crosswise opposite sides of the part main body 1 respectively. An outer electrode conductor film 3 is formed on all the two crosswise opposed sides of the part main body 1. Then, the disused part (part not used as outer electrodes) of the conductor film 3 is irradiated with infrared laser rays 4, the irradiated part of the conductor film 3 is heated to disappear, and four stripe-like outer electrodes 5 connected to the led ends 2 of the discrete circuits inside the part main body 1 respectively are formed on the two crosswise opposite sides of the part main body 1.
