A soccer ball includes a plurality of sheet plates connected with each other and a plurality of reinforcement strips connected with the sheet plates. Each of the sheet plates has a plurality of connecting sides, and the opposite connecting sides of any two adjacent sheet plates are connected to construct a plurality of connections. Each of the reinforcement strips is bonded onto a respective one of the connections to reinforce the strength of the respective connection of the sheet plates. Thus, the reinforcement strips encompass the connections of the sheet plates completely so that the connections of the sheet plates are reinforced and limited by the reinforcement strips to prevent the connections of the sheet plates from being torn or broken due to a stress concentration so as to enhance the lifetime of the soccer ball. |
