To provide a printing blanket that enables good and rapid printing on a nonlinear printing surface (e.g., a doughnut-shaped outer surface). A printing blanket 10 is ring-shaped in plan view and includes an attachment surface 1, an inward facing surface 2, an outward facing surface 3, the inward and outward facing surfaces 2 and 3 being protruding surfaces, and ridge lines 4 which smoothly connect the inward facing surface 2 and the outward facing surface and which are substantially arc-shaped in section. A circle connecting the ridge lines 4 serves as a pitch circle 5 having a curvature radius P5. The printing blanket is suitable for printing on a steering wheel 20 having a pitch circle 8 having a curvature radius P8 which substantially coincides with the curvature radius P5.
