18 Claims

1. A pin terminal, comprising:

a bar-like base material; and

a plating layer covering a predetermined region of the base material,

wherein:

a constituent material of the base material is pure copper or a copper alloy,

the plating layer includes a tin-based layer made of metal containing tin,

one end side of the base material includes a tip covering portion,

the tin-based layer includes the tip covering portion,

the tip covering portion covers an entire region in a circumferential direction on the one end side of the base material, and

a difference (t₁−t₂) between a maximum value t₁and a minimum value t₂of a thickness of the tip covering portion measured at a measurement location set at a spot of 1 mm from one end of the pin terminal along a longitudinal direction of the pin terminal is 0.20 μm or more.
