Abstract: A showcase includes a main body a front face of which is covered by a door (6) having a glass plate (5), so that the front face is opened and closed by the door (6), in which a rod-shaped illumination module (16) is disposed in each of grooves (14) of left and right supporting column frames (12) that define an opening on the front face of the main body that is opened and closed by the door (6). Each of the illumination modules (16) has LED lamps each constituted by an LED and a lens, and arranged at regular intervals and integrated together. Thus, commodities (7) arranged along the front end of each shelf (8) are illuminated with direct light from the illumination modules (16) and reflected light from the glass plate (5). By this configuration, it is possible to reduce variation of illuminance among commodities and shading and shadows between the commodities arranged along the front end of each shelf.
