PROBLEM TO BE SOLVED: To provide a terminal having a new barrier section against solder soaking up which has high solder soaking up prevention effect, and its manufacturing method. SOLUTION: This terminal has the barrier section against solder soaking up, and C of 50-70% and Ni of 20-40% on an average are detected from various regions when measured by an Auger electron spectrometer. This terminal is manufactured by a method performing the following processes of (a)-(c) one by one: (a) a process in which nickel backing plating and finishing gold plating is applied to the base material of the terminal, (b) a process in which the surface of the terminal is treated by a sealing treatment liquid containing C in its components, (c) a process in which one or more spots of the terminal are irradiated with laser and the barrier sections against solder soaking up are formed at such spots.
