According to an aspect, a lighting apparatus includes a lighting unit including a long-shaped housing that has upper and lower openings and has an outer surface formed as a convex surface when seen in a cross-section perpendicular to a longitudinal direction, and a semiconductor light emitting device disposed inside the housing so as to emit light toward the lower opening. Further, the lighting apparatus includes a holding unit including a holding member in which at least a portion of a surface is formed as a concave surface corresponding to the convex surface when seen in a cross-section perpendicular to the longitudinal direction of the lighting unit. When seen in the cross-section, the convex surface has, in a region that faces the concave surface, a portion that is brought into contact with the concave surface, and a portion that is not brought into contact with the concave surface. |
