PURPOSE: To simply and reliably prevent solder run-up when fixing components on a circuit board or the like, and prevent the deterioration of a function and performance by arranging oxide films on local surface parts of terminal parts of plural electronic part terminals fixed to an insulator CONSTITUTION: In an insulator 1 composed of plastic or the like, connectors 2 are installed in a fixing part 22, and contact parts 21 with the other connectors and terminal parts 23 are formed. Next, these terminal parts 23 are inserted into through holes of a circuit boards 3 for connection, and positioned through a stand 4. Next, the terminal parts 23 are fixed on a circuit of the circuit board 3 by solder 5. In that case, oxide films 231 are arrange on local surface parts of the terminal parts 23. These oxide films 231 are preferably arranged over the whole circumference of the terminal parts in a part on the terminal part side reaching an insulator push-in part from a board inserting part, and can be locally formed by heating by irradiation of a laser beam or the like in an oxidizing ambience such as in the atmosphere. |
