The present invention relates to a cooking hob including at least one griddle plate (10). The griddle plate (10) includes a central portion (12). The central portion (12) is formed as a metal plate. The griddle plate (10) includes a frame portion (14) enclosing the central portion (12). The coefficient of thermal expansion for the material of the frame portion (14) is higher than the coefficient of thermal expansion for the material of the central portion (12). A join patch (16) connects the central portion (12) and the frame portion (14), so that the central portion (12) and the frame portion (14) form a rigid body. Further, the present invention relates to a corresponding griddle plate.
