A disk brake includes a caliper body having a cylinder portion (25) with a cylindrical shape. The cylinder portion (25) has a bore (30) with a bottom (34) formed by integrally joining together an opening peripheral edge (98) at the bottom side of the cylinder portion (25) and a bottom cover member (92) to be fitted to the opening peripheral edge (98) through friction stir welding. The bottom cover member (92) has a disk shape and is friction-stir-welded along the outer periphery thereof. The terminating point of the friction stir welding is within the boundaries of the bottom cover member (92).

In a wiring laminate portion of a multilayer wiring substrate, a solder resist layer having a plurality of openings is disposed on a main surface side of the laminate structure, and connection terminals are embedded in an outermost resin insulation layer in contact with the solder resist layer. Each of the connection terminals comprises a copper layer and a metallic layer formed of at least one type of metal other than copper. A main-surface-side circumferential portion of the copper layer is covered by the solder resist layer. At least a portion of the metallic layer is located in a recess in a main-surface-side central portion of the copper layer. At least a portion of the metallic layer is exposed via a corresponding opening.

A multilayer wiring substrate includes a laminate structure in which resin insulation layers and conductor layers are alternately laminated. The resin insulation layers include first-type resin insulation layers, and second-type resin insulation layers, each of which contains an inorganic material in a larger amount and is smaller in thermal expansion coefficient as compared with first-type resin insulation layers. On a cross section of the laminate structure taken along a thickness direction thereof, the ratio of a total thickness of the second-type resin insulation layers located in an area A2 to a thickness corresponding to the area A2 is greater than the ratio of a total thickness of the second-type resin insulation layers located in an area A1 to a thickness corresponding to the area A1. The laminate structure is warped such that the laminate structure is convex toward the side where the second main face is present.

A Ni-base alloy large-size member comprises a base material having strip-shaped carbide segregation, and a homogeneous modified layer formed on a welding groove surface by treatment using Friction stir processing and solution treatment. In addition, a Ni-base alloy welded structure is manufactured by welding the Ni-base alloy large-size member with other member constituting the Ni-base alloy welded structure, such as a member formed of ferrite steel or another Ni-base alloy large-size member under the condition that weld penetration depth is shallower than the thickness of the modified layer.
