Abstract

PROBLEM TO BE SOLVED: To provide a connector equipped with a solder ball in which mounting work is easy, and multi-core formation is also easy. SOLUTION: A copper pattern 4 is provided in the periphery of a through hole made in a board 3, and the through hole of the board 3 is fitted to a contact 2 protruded from an insulator 1. After flux 6 is transcribed onto the end face of the contact 2 and the copper pattern 4, a formed solder ball 5 is mounted on the flux 6 so as to conduct reflow so that the solder ball 5 is fused to the contact 2.
