Abstract: The layered structure of the present invention is a layered structure formed by directly layering a resin cured layer (ii) containing a curable resin (E) having a urethane bond, on a molded body (i) composed of a polypropylene-based resin composition, wherein the polypropylene-based resin composition contains 5 to 47 parts by mass of a propylene-based polymer (A) having an MFR of 50 to 150 g/10 min, and an amount of a decane-soluble portion of 6 to 15% by mass, 20 to 30 parts by mass of a propylene homopolymer (B) having an MFR of 10 to 500 g/10 min, 23 to 30 parts by mass of an ethylene/α-olefin copolymer (C) being a random copolymer of ethylene and an α-olefin having 4 to 8 carbon atoms, and having a density of 0.850 to 0.880 g/cm3, an MFR of 0.5 to 30 g/10 min, and a melting point peak of 110° C. or more, and 30 to 40 parts by mass of an inorganic filler (D).

Abstract: A two-pack urethane-based adhesive that includes a second-pack liquid in which liquid components are inhibited from bleeding out and which can be inhibited from decreasing in thixotropic properties, and that gives cured products having, after aging, excellent adhesiveness. The two-pack urethane-based adhesive including a first-pack liquid, which includes a urethane prepolymer having an isocyanate group, and a second-pack liquid, which includes water, an active hydrogen compound (which is not water) having an active hydrogen capable of reacting with the isocyanate group, and cellulose nanofibers, wherein the first-pack liquid and the second-pack liquid each independently contain carbon black and/or an inorganic-based filler, the content of the cellulose nanofibers being 0.1-1.5 mass % with respect to the content of the water.
