摘要： A substrate for suspension comprises a metallic substrate, an insulating layer formed on the metallic substrate, a conductor layer formed on the insulating layer, and a cover layer covering the conductor layer. The insulating layer and the cover layer are formed from different materials, whose coefficients of hygroscopic expansion are in the range between 3×10−6/% RH and 30×10−6/% RH. The difference between the coefficients of hygroscopic expansion of the two materials is 5×10−6/% RH or less.

摘要： The present invention provides a substrate for suspension that includes a first structural part including a metal supporting substrate, an insulating layer, a wiring layer, and a cover layer, and a second structural part formed so as to extend continuously from the first structural part and has no metal supporting substrate. A position of an edge of an upper surface of the insulating layer coincides with a position of an edge of the lower surface of the cover layer or the position of the edge of the upper surface of the insulating layer is positioned on a side closer to the wiring layer than to the position of the edge of the lower surface of the cover layer at a boundary region between the first structural part and the second structural part.
