A circuit board includes a base substrate and an electrical pattern. The electrical pattern is arranged on the base substrate and includes a plurality of conductive patterns and a plurality of connection pads. Each conductive pattern is electrically connected to at least one connection pad. The electrical pattern is composed of a first conductive layer and / or a second conductive layer, wherein the second conductive layer covers a side of the first conductive layer away from the base substrate and two sides of the first conductive layer in the extension direction thereof. The electrical pattern further includes at least one of a first protective layer and a second protective layer, wherein the first protective layer and the second protective layer are used for improving the oxidation resistance of the electrical pattern. Either of the first protective layer and the second protective layer can form a second intermetallic compound with solder.
