摘要： A lead member includes a lead conductor having a first main surface and a second main surface opposite to the first main surface. The lead member includes a resin portion that covers the first main surface, the second main surface, and two side surfaces that are between both ends of the lead conductor, while exposing the both ends of the lead conductor in a first direction. The lead conductor includes a metal substrate and a surface treatment layer formed on at least a portion of a surface of the metal substrate, the surface treatment layer including chromium, oxygen, and fluorine. A moisture content of a portion of the surface treatment layer exposed from the resin portion, as measured by coulometric Karl Fischer titration at a vaporization temperature of 220° C., is 5.0 μg/cm2 or less.

摘要： In manufacturing a printed circuit board using a semi-additive method, a removal liquid that has been used in removing a nickel-chromium-containing layer (5) is regenerated by contacting the removal liquid with a chelate resin having a functional group represented by a following formula (1) :
where a plurality of Rs are identical divalent hydrocarbon groups having 1 to 5 carbons, and a portion of hydrogen atoms may be substituted with halogen atoms.-
