PROBLEM TO BE SOLVED: To provide a suspension board with circuits that can adjust a posture angle with a high degree of accuracy while ensuring reliability of a wiring pattern, and a method for manufacturing the suspension board with circuits.SOLUTION: A thick portion 41a having a first thickness and a thin portion 41b having a second thickness on a base insulating layer 41 are formed on a conductive support substrate 10. The second thickness is smaller than the first thickness. A boundary surface 41c is formed between an upper surface of the thick portion 41a and an upper surface of the thin portion 41b. A boundary line between the upper surface of the thick portion 41a and the boundary surface 41c extends in a first direction. Write wiring patterns W1, W2 and read wiring patterns R1, R2 are formed to extend on the thick portion 41a and the thin portion 41b of the base insulating layer 41. The lateral sides of the write wiring patterns W1, W2 and the read wiring patterns R1, R2 extend in a second direction that intersects with the first direction, and the second direction forms an angle of not less than 60 degrees and not more than 90 degrees with the first direction. |
