An egg surface inspection apparatus (1) includes a conveying unit (2), a light projecting unit (3), an imaging unit (4) and a determination unit (5). The conveying unit (2) conveys an egg (E) while rotating the egg (E) with the egg's longitudinal axis serving as a rotation axis. The light projecting unit (3) projects linear light extending in a direction traversing a conveying direction (A) of the conveying unit (2). The imaging unit (4) recognizes the egg (E) irradiated with the linear light by the light projecting unit (3) as a two-dimensional image. The determination unit (5) determines a state of a surface of the egg (E) based on positional data of the linear light imaged by the imaging unit (4).
