Provided are a laminated body and a laminated body manufacturing method that can improve adhesiveness between a resin layer and a seed layer. The laminated body has a substrate, a first wiring layer, a resin layer, and a second wiring layer in this order, and the second wiring layer includes at least an adhesive layer and a seed layer in this order.

The present invention achieves chemical bonding by means of a joined film made of oxides formed on a joined surface. In a vacuum container, amorphous oxide thin films are respectively formed on smooth surfaces of two substrates, and the two substrates overlap such that the amorphous oxide thin films formed on the two substrates come into contact with each other, thereby causing chemical bonding involving an atomic diffusion at a joined interface between the amorphous oxide thin films to join the two substrates.

Provided is a method of manufacturing a ZnMg alloy plated steel having excellent plating adhesion and corrosion resistance. The method includes: sequentially forming a first Zn plating layer, a second Mg plating layer, and a third Zn plating layer on base steel by a physical vapor deposition (PVD) method to provide a plated steel material; heating the plated steel material for alloying heat treatment to provide an alloy plated steel material; and cooling the alloy plated steel material. In the providing of the plated steel material, the second Mg plating layer has a thickness of 30% to 35% of the sum of thicknesses of the first Zn plating layer, the second Mg plating layer, and the third Zn plating layer, and the first Zn plating layer has a thickness of 1.1 to 4 times a thickness of the third Zn plating layer.
