本発明は、自動機等による取り扱いの容易なチップ抵抗
器を製造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a chip resistor that can be easily handled by an automatic machine or the like.
従来チップ抵抗器を製造する方法としては、第1図に示
したように、一枚の絶縁平板1の縦横に切り込み2,3
を入れ、横の切り込み2に沿って先づ平板1を分断し、

今度は切り込み3に沿って平板1を分断して、複数個の
チップ抵抗器とする方法があった。As shown in FIG. 1, the conventional method for manufacturing a chip resistor is to make cuts 2 and 3 in the vertical and horizontal directions of a single insulating flat plate 1.
, cut the flat plate 1 along the horizontal cut 2,
Terminal electrodes 4 and 5 are provided on the end faces in the width direction of the divided long flat plate 1 and in the vicinity thereof, and then each electrode on one plane of the flat plate 1 is provided so as to bridge the terminal electrodes 4 and 5. There was a method in which the resistor 6 was provided in a portion divided by the notch 3, and finally, the flat plate 1 was divided along the notch 3 to form a plurality of chip resistors.
ところが上述の方法により得られたチップ抵抗器は、平

として、その凸部により端子電極4,5が分断(例えば

合であった。However, in the chip resistor obtained by the above method, since the flat plate 1 is first divided along the notches 2, the end surface on which the terminal electrodes 4 and 5 are provided becomes an uneven surface as shown in the second figure, and the terminal The electrodes 4 and 5 could not be provided with a uniform thickness, and the terminal electrodes 4 and 5 were sometimes separated by the convex portion (for example, at part A), which was very inconvenient.

提供せんとするものである。In addition, since this secondary type is ultimately further divided by the notch 3, virtually the entire side surface of the chip resistor becomes an uneven surface. For example, when handling this with an automatic machine such as a parts feeder, However, they also had the disadvantage that they could get stuck with each other, making it impossible to operate them smoothly. Furthermore, in this conventional method, since the cutting is done by bending along the notches 2 and 3, burrs are generated on the cutting surface, and when this is placed on a printed circuit board (not shown), it does not overlap with the board surface. There was also a drawback that a gap was created between the two, making it impossible to install them properly. The present invention has been made in view of the above-mentioned points.Both end faces in the width direction of the longest flat plate are curved, terminal electrodes are provided on both curved end faces, and a terminal electrode is provided on one plane of the long flat plate. , a chip characterized in that a resistor is provided to bridge between the terminal electrodes, and then the elongated flat plate is cut with a slicer in the width direction to separate the resistor into a plurality of pieces. The present invention aims to provide a method for manufacturing a resistor.

させて付与したものである。In the present invention, first, a long flat plate 11 as shown in FIG. 3 is prepared. This elongated flat plate 11 is configured such that both end faces in the width direction exhibit curved surfaces. This curved surface can be advantageously formed, for example, at the same time as powder molding or by chamfering after molding. Next, this long flat plate 1
1, as shown in FIG. 4, terminal electrodes 12 and 13 are provided on the entire area of both opposing curved end surfaces, respectively. In this case, it is preferable that the terminal electrodes 12 and 13 are provided not only on the curved end surface but also slightly on the flat surface of the substrate 11. Next, as shown in FIG. 5, a plurality of resistors 14 are provided on one plane of the elongated substrate 11 so as to bridge between the opposing terminal electrodes 12 and 13. Each resistor 14
Both ends thereof are electrically conductively connected to both terminal electrodes 12 and 13. Finally, connect the terminal electrodes 12, 13 and the resistor 1 like this.
4 is cut in the width direction between the resistor elements 14 using, for example, a rotary slicer (not shown) to separate each resistor element 14, as shown in the sixth figure. multiple chip resistors. FIG. 7 shows another example of the present invention, in which terminal electrodes 12 and 13 are provided on both curved end surfaces of a long flat plate 11 in a manner that matches the number of resistors 14. .

Note that the above embodiments and drawings are for embodying the present invention, and are not limited thereto in any way. In short, it is sufficient to use a long flat plate with curved end surfaces and to cut it to obtain each resistor using a slicer, and some design changes are allowed. Furthermore, the slicer is not limited to a rotary type. As described above, in the chip resistor obtained by the method of the present invention, the end surface to which the terminal electrodes are provided is previously formed into a curved surface, so that the state in which the terminal electrodes are provided is extremely stable.
