The purpose of the present invention is to provide a supported platinum catalyst, which has a high ratio of diffraction peak intensity of a Pt (220) plane and has excellent oxidation resistance, with a simple production method without using a polymer. This supported platinum catalyst comprises a carbon carrier and platinum particles supported by the carbon carrier, wherein the platinum particles have a ratio of diffraction peak intensity of a (220) plane with respect to the total of the diffraction peak intensities of a (111) plane, a (200) plane, and the (220) plane by X-ray diffraction of 0.128 or more. 提供一种在不使用聚合物的情况下利用简便的制造方法而Pt(220)面的衍射波峰强度的比例高且耐氧化性也优异的负载铂催化剂。本发明的负载铂催化剂包含碳载体、以及负载于所述碳载体上的铂微粒子，所述铂微粒子中，相对于通过X射线衍射而获得的(111)面、(200)面及(220)面的衍射波峰强度的合计的、所述(220)面的衍射波峰强度的比为0.128以上。
