The invention provides an image projection device and a vehicle lamp, which can restrain disconnection caused by wrong connection of a flexible cable. An image projection device is provided; a digital micromirror device (102) provided with a plurality of minute mirrors reflects light and projects an image. Comprising: a mirror mounting substrate (101a) on which a digital micromirror device (102) is mounted; a power source mounting substrate (101b) formed separately from the mirror mounting substrate (101a); and a flexible cable (108) that electrically connects the mirror mounting substrate (101a) and the power source mounting substrate (101b), the wiring layers of the flexible cable (108) being disposed in bilateral symmetry.
本发明提供一种图像投影装置及车辆用灯具,能够抑制因柔性电缆的误连接导致的断线的发生。一种图像投影装置,由具备多个微小反射镜的数字微镜器件(102)反射光而对图像进行投影,其中,具备:反射镜搭载基板(101a),其供数字微镜器件(102)搭载;电源搭载基板(101b),其与反射镜搭载基板(101a)分体形成;柔性电缆(108),其将反射镜搭载基板(101a)和电源搭载基板(101b)电连接,柔性电缆(108)的配线层左右对称地配置。
