Terminal Fitting

摘要

A terminal fitting (17) includes a welded part (26) to which the conductor part of an electric wire is ultrasonically welded, and a board-like mounting part (23) which is formed integrally with the welded part in the axial direction and which a through hole (21) penetrates in the thickness direction. A contour, when viewed from the penetration direction, of the through hole (21) is formed of a large radius circle (31), a small radius circle (33) whose radius is smaller than that of the large radius circle, and two tangent lines (35, 37) which respectively connect the two circles, and the small radius circle is located closer to the welded part than the large radius circle.
