An electronic part, particularly a microstructure contact having an overall length of the order of 5 mm for an electrical connector or the like is provided with a nickel oxide layer portion having a nickel oxide layer of the order of 50 to 5000 .ANG. in thickness formed by anode oxidizing process using a solution mainly consisting of an alkaline solution. The nickel oxide layer portion is located between a terminal portion of the electronic part to be soldered as in a surface mounting process and a contact portion continuous to and extending from the terminal portion. The nickel oxide layer has a width of the order of 0.2 to 1 mm in the longitudinal direction of the contact and has a performance preventing the flowing of molten solder, thereby effectively preventing the flowing and wicking due to wetting of solder of the solder-plated portion toward the other portions as in the surface mounting process.
