PCB terminal, connector, wiring harness with connector and board unit

A PCB terminal, comprising:

• a rod-like base material;
• and
• a plating layer covering a predetermined region of the base material,
• wherein:
• a constituent material of the base material is a copper alloy containing 20% by mass or more of zinc,
• the plating layer includes a first coating portion and a second coating portion,
• the first coating portion includes an entire peripheral layer entirely covering a region on side of a first end part, out of both end parts of the base material, in a circumferential direction of the base material,
• the second coating portion partially covers a region on side of a second end part, out of the both end parts of the base material, in the circumferential direction of the base material,
• the entire peripheral layer includes a tin-based layer and a barrier layer,
• the tin-based layer includes a pure tin layer constituting an outermost surface of the first coating portion, and
• a constituent material of the barrier layer is pure nickel or a copper-tin alloy containing copper and tin.
