Abstract:
1. An illuminating device comprising: point light sources arranged in a line, that emit light; an optical guide member formed by injection molding and one end face of the optical guide member facing the point light sources, that guides light emitted from the point light sources to a surface to be illuminated such that the light emitted from the point light sources is incident on the one end face of the optical guide member and the light incident on the one end face of the optical guide member exits from the other end face of the optical guide member, which opposes the one end face; and first pin marks formed by projection pins used when removing the optical guide member when injection molding the optical guide member, the first pin marks being formed on one of faces of the optical guide member, which contact with the one end face facing a direction along which the point light sources are arranged and which extend in the direction along which the point light sources are arranged, and being formed in positions offset from the point light sources in the direction along which the point light sources are arranged such that each of the first pin marks is formed at a side of the one end face and at a substantially center position between two adjacent point light sources in the direction along which the point light sources are arranged so as to suppress leakage of the light incident on the one end face to the outside of the optical guide member by the first pin marks.
