    • A heating cooker includes: a top plate on which a cooking container to be heated is placed; an outer case as a main body having an upper surface on which the top plate is placed; a heater heating the cooking container; and a light emitting device disposed in the outer case, for displaying the heating state. The top plate includes: a glass substrate having a transparent light-transmitting low-expansion crystallized glass made mainly of Li2O—AL2O3—SiO2 and having β-quartz solid solution, having a crystal size smaller than the wavelength of visible light; a design layer having a black-based color disposed on an undersurface of the glass substrate; a diffusion region disposed partially on an undersurface of the design layer, for diffusedly emitting light from the light emitting device; and a light-blocking layer disposed on the undersurface of the design layer other than the diffusion region, for blocking light from below.
    • 一种加热烹调器包括:顶板,放置有待加热的烹饪容器; 作为主体的外壳,具有放置上板的上表面; 加热烹饪容器的加热器; 以及设置在外壳中的用于显示加热状态的发光器件。 顶板包括:具有晶体尺寸小于可见光波长的玻璃基板,其具有主要由Li 2 O -Al 2 O 3 -SiO 2制成并具有β-石英固溶体的透明低透光性低膨胀结晶玻璃; 设置在所述玻璃基板的下表面上的具有黑色的设计层; 扩散区,其部分地设置在所述设计层的下表面上,用于从所述发光器件扩散地发射光; 以及设置在除了扩散区域之外的设计层的下表面上的遮光层,用于阻挡来自下面的光。
