Provided are a polymeric article and a composite article capable of obtaining favorable texture with a high resilience by using thermoplastic elastomer. A composite article includes: a first member; and a second member having a plate-shaped portion and a plurality of protrusions protruding from the back surface of the plate-shaped portion and having protruding ends contacting the first member, and cushioning properties are imparted to the composite article by elastic deformation of the second member. The plate-shaped portion and the plurality of protrusions are integrally made of solid thermoplastic elastomer or slightly-foamed thermoplastic elastomer with an expansion ratio of 1.1 or less, the thermoplastic elastomer having an impact resilience modulus of 30 to 90% at 23°C measured in accordance with JIS K6255, and a hysteresis loss rate measured at 23°C by compressing and depressurizing the composite article at a speed of 60 mm/min is 28% or less.
