PROBLEM TO BE SOLVED: To provide a composite in which platinum nanoparticles having a desired shape and particle diameter are stably dispersed in a polymer, and a simple manufacturing method therefor. SOLUTION: The composite is a platinum nanoparticle-polymethacrylate composite in which platinum nanoparticles having various shapes or diameters are dispersed in a solid polymethacrylate. The platinum nanoparticles are preferably deformed ones in the form of a chestnut bur or having irregularities. Further, the composite can be obtained by irradiating a polymethacrylate containing a platinum complex with light in a hydrogen atmosphere, and then heating the irradiated polymethacrylate (ester) at a temperature of≥120°C in a hydrogen atmosphere to reduce it. By adjusting at least one of the light irradiation time and the heating time for reduction, the shape and particle diameter of the platinum nanoparticles to be obtained can be varied.
