PROBLEM TO BE SOLVED: To absorb a sound wave generated in an engine room, and to also relieve impact added to a pedestrian when colliding with the pedestrian.SOLUTION: At least a part of an automobile hood as an automobile exterior article is constituted of a resin honeycomb structure. The honeycomb structure comprises a honeycomb part composed of a plurality of cells 24 mutually partitioned by a partition wall 14 and forming a cylindrical shape by extending in the inner-outer directions, an inner plate part 31 arranged inside the honeycomb part and an outer plate part 32 arranged outside the honeycomb part and sealing the respective cells 24 by sandwiching the honeycomb part from both inner-outer sides together with the inner plate part 31. The respective partition walls 14 are provided with a communication hole 18 for communicating an engine room 10 with an inside space of the cells 24, and are also provided with an absorption part (a connection plate part 17) for absorbing energy by being deformed on the periphery of the communication hole 18 when external force is added toward the inside via the outer plate part 32. |
