A drawing apparatus includes an object insertion portion to which an object is inserted, the object being a finger or a toe having a nail; a light source unit configured to emit light to the nail of the object inserted into the object insertion portion; an image acquisition unit configured to acquire image data of the object with the nail illuminated by the light; and a control unit.The light source unit includes at least one light source disposed obliquely above the nail so that a shadow is formed near a border between the nail and a cuticle part on the root side of the nail by the light emitted from the light source.The control unit detects a position of the border based on the shadow and detects a region of the nail based on the position of the border.
