PROBLEM TO BE SOLVED: To suppress insulation performance from being deteriorated while securing connection reliability.SOLUTION: A press-fit terminal is inserted into a through-hole 22 provided on a circuit board to be held inside the through-hole 22, has a first contact part 14A and a second contact part 14B which elastically come into contact with an inner peripheral surface of the through-hole 22, and in a cross-sectional view of a cross-section that is orthogonal to the insertion direction, a value obtained by dividing a radius of curvature of the second contact part 14B by a radius of curvature of the first contact part 14A becomes 0.75 or less. The first contact part 14A and the second contact part 14B are arranged so that the first contact part 14A and the second contact part 14B become adjacent to each other between the neighboring press-fit terminals. This causes the contact part having small contact pressure applied to the inner peripheral surface and the contact part having large contact pressure applied to the inner peripheral surface to become adjacent to each other between the neighboring through-holes 22. As a result, damaged portions D1, D2 of the circuit board between the neighboring through-holes 22 can be suppressed from approaching to each other.SELECTED DRAWING: Figure 5 |
