A luminous safety ball, comprising:

• an inner glowing body;
• a foam sphere covering the inner glowing body;
• and
• a cover layer covering the foam sphere;
• wherein the inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form lights with different brightness thereon;
• wherein the inner glowing body has a surrounding side wall, and a top wall and a bottom wall disposed opposite to each other in a vertical direction and connected to the surrounding side wall;
• wherein the thickness of the foam sphere at a position corresponding to the surrounding side wall of the inner glowing body is smaller than that at a position corresponding to the top wall of the inner glowing sphere;
• wherein the thickness of the foam sphere at the position corresponding to the surrounding side wall is smaller than that at a position corresponding to the bottom wall of the inner glowing sphere;
• wherein at least one seam gap and a plurality of stitch holes positioned on two sides of the at least one seam gap are formed on the cover layer, and the stitch holes are positioned corresponding to the surrounding side wall of the inner glowing body;
• wherein the surrounding side wall of the inner glowing body has a groove recessed inwardly, the groove surrounds the surrounding side wall, and the stitch holes are positioned on two sides of the groove.
