- each of the meandering precursors 300 cut out from the substrate 100 is put into a liquid tank 500 containing an etching solution such as a piranha solution and impregnated with the etching solution. Etching by this (step S4).
- the piranha solution is usually a mixture of ion-exchanged water, concentrated sulfuric acid, hydrogen peroxide, and a small amount of additives if necessary.
- the amount of sulfuric acid and hydrogen peroxide mixed with the ion-exchanged water is not limited, but as an example, the concentrated sulfuric acid (undiluted solution) is 5% by weight and the 30% hydrogen peroxide is 6 with respect to the ion-exchanged water. It can be a mixture of% by weight and 1 to 2% by weight of a small amount of additives.
- the etching time is appropriately determined depending on the concentration of the etching solution, the thickness of the precursor 300 to be treated, the amount of corrosion target on the side surface 160 thereof, and the like. For example, in the case of manufacturing a thin copper part having a thickness of 100 ⁇ m. When the etching solution mixed under the above-mentioned example conditions is used, the etching time may be about 3 minutes.
- the etching solution used in step S4 is a mixture of ferric chloride, hydrochloric acid and, if necessary, a small amount of additives in ion-exchanged water.
- 35% hydrochloric acid is 15% by weight to 25% by weight (for example, 20% by weight) with respect to 47 boume ferric chloride (stock solution) with respect to ion-exchanged water.

- the cathode electrode 740 is placed in the etching solution of the liquid tank 600.
- the precursor 300 is subjected to electrolytic polishing treatment under an applied voltage of, for example, about 1 V to 10 V (step S5).
- the amount of polishing of the precursor 300 by electrolytic polishing in step S5 is smaller than the amount of corrosion of the precursor 300 by etching in step S4.
- the concentration of the former etching solution may be made higher than the concentration of the latter etching solution, the impregnation time of the former and the impregnation time of the latter may be longer than the impregnation time of the latter, or a combination thereof may be mentioned.

- the impregnation time is lengthened or the voltage value of the applied voltage is increased. It can also be handled by raising it.
- ion-exchanged water containing 5% by weight to 15% by weight of sulfuric acid is used as the electrolytic solution, and when the voltage value of the applied voltage is kept under the above conditions, the impregnation time is, for example, 30.
- the impregnation time can be set to 2 to 5 minutes, and the voltage value of the applied voltage can be set to, for example, 1 V to 10 V when the impregnation time remains the same.
- the protective layer 200 is desorbed from each of the precursors 300 after electropolishing (step S6).
- the desorption method is not particularly limited, but for example, the protective layer 200 may be corroded, but the precursor 300 itself may be impregnated with a solution that does not corrode. In this way, the metal processed part 400 of the present embodiment is completed.

- the side surface 160 has a concave shape.
- the corners of the front surface 120 and the side surface 160 and the corners of the back surface 140 and the side surface 160 are sharp. Therefore, when the corner portion comes into contact with the peripheral member, the peripheral member may be damaged or shavings may be generated.
- the side surface 160 is totally corroded, but the corners are particularly corroded. The amount is large and the result is chamfered. On the side surface 160, corrosion of about 10 ⁇ m was confirmed at the central portion, and corrosion of 20 ⁇ m, which was about twice that, was confirmed at the corner portion.
- both the corner portion between the front surface 120 and the side surface 160 and the corner portion between the back surface 140 and the side surface 160 are chamfered to form a slope 180. Therefore, focusing on the side surface 160, the cross section becomes convex due to the presence of the slope 180. Since the slope 180 is not polished or the like, no processing marks are left on the slope 180.
- the surface roughness of the side surface 160 and the slope 180 is usually relatively higher than that of the front surface 120 and the back surface 140.
- the surface roughness of the side surface 160 and the slope 180 can be suppressed, and rather, the surface roughness is relatively low as compared with the front surface 120 and the back surface 140. There may be no surface roughness. In any case, the surface roughness of the side surface 160 and the slope 180 is different from the surface roughness of the front surface 120 and the back surface 140.
- the metal processed component 400 described above may be used as a contact pin in a semiconductor wafer inspection device or the like, as a metal plate in a speaker, as a rectifying plate having a mesh portion, or as a heat sink. it can.
