<p>Provided is a portable terminal device that has an emission-element light guide structure that reliably performs blocking of light inside and outside of a light path, and enables the reduction of force applied from the inside of a panel. The portable terminal device is equipped with the following: emission elements (71-73) for emitting light or detecting incident light; a substrate (70) on which the emission elements (71-73) are provided; a panel (10) disposed facing the substrate (70); and a partition member (60) that has light blocking properties and elasticity, is fixed in an elastically-deformed state by being sandwiched between the substrate (70) and the panel (10), and partitions the light paths that are between the panel (10) and the emission elements (71-73). The partition member (60) employs a configuration having notch sections (E1a, E1b, E2a-E2c, E3a, E3b) that become, at an end part of the notch sections where the substrate (70) or the panel (10) comes into contact with the notch sections, thinner than an intermediate region of the substrate (70) and the panel (10).</p> |
