PROBLEM TO BE SOLVED: To provide a substrate for suspension capable of preventing disconnection of a second wiring layer provided on a first wiring layer across an insulating layer and improving electrical characteristics.SOLUTION: A substrate for suspension includes: a metal substrate 20; a first insulating layer 22 provided on the metal substrate 20; a first wiring layer 10 provided on the first insulating layer 22; a second insulating layer 24 provided on the first wiring layer 10; and a second wiring layer 12 provided on the second insulating layer 24. In an overlapping region 14 where the second wiring layer 12 is disposed above the first wiring layer 10, the second wiring layer 12 has a wide width part 16 in which wire width W1 is wider than wire width W2 of other parts of the second wiring layer 12. |
