Chip-like electric component and method for manufacturing the same

Abstract

Provided is a chip-like electric component, such as a chip resistor, which is easily manufactured even without increasing cost and eliminates cracks and breakage of an insulating substrate. A pair of surface electrodes (21, 23) are formed such that the thickness increases from a resistive layer (13) toward a pair of ends (30) of an insulating substrate (29) positioned in a direction where the pair of surface electrodes (21, 23) are arranged. A plating accumulating section (S) is formed between the surface electrodes (21, 23) and the insulating protection layer (15). At the time of forming one or more plating layers (33), a plating metal is accumulated in the plating accumulating section (S), and steps formed between the soldering electrode sections (21, 23, 27, 33) and the insulating protection layer (15) can be made small to a certain extent by the plating layer (33).

Description

technical field [0001] The present invention relates to a chip-shaped electrical component and a manufacturing method thereof. Background technique [0002] In chip resistors, which are one type of relatively large chip-shaped electrical components, resistors and the like are formed with thick films, and all electrodes for soldering are also formed with thick films. In addition, in a resistor having a relatively small size, electrodes and resistors may be formed only by a thin film forming technique. In addition, in resistors with a relatively small size, soldering electrodes may be formed by a combination of a thick film and a thin film. [0003] In the method of manufacturing a chip resistor described in Japanese Unexamined Patent Application Publication No. 63-172401 (Patent Document 1), in order to obtain individual chip substrates, an alumina substrate for multiple acquisition that can be cut and separated is used. First, a plurality of thick-film resistor layers made...
