<P>PROBLEM TO BE SOLVED: To improve connection strength of a circuit board and a terminal fitting. <P>SOLUTION: While a board connection part 21 of a terminal fitting 20 is inserted in a through hole 11 of a circuit board 10, a pair of elastic flexion parts 22 formed on the board connection part 21 are elastically formed to approach to each other, and are in elastic contact with an inner periphery of the through hole 11. A copper plated layer 25 formed on outer faces of the elastic flexion parts 22 and a board side tin plated layer 13 formed on the inner periphery of the through hole 11 (a tin plated layer on a side, on which the copper plated layer is not formed) are alloyed to hold the board connection part 21 in the through hole 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
