Abstract: Disclosed are: a multi-sided luminous lighting member which is mounted to a structure having a complex three-dimensional shape, such as an automobile, so as to be used for the purpose of lighting, signaling, decoration, and the like; and a three-dimensional lighting device using the same. The lighting member according to an aspect of the present invention is a light-transmitting light guide member having a plurality of light emitting surfaces and comprises: a light guide member having a light incident portion which is at least one of the plurality of light emitting surfaces, a first light exit portion which is at least one other surface opposite to the light incident portion among the plurality of light emitting surfaces, and a second light exit portion which is at least one other surface placed laterally in the direction in which light incident to the light incident portion travels toward the first light exit portion, wherein light incident to the light incident portion is emitted from the first light exit portion and the second light exit portion; at least one light emitting diode disposed adjacent to the light incident portion such that light is incident to the light incident portion; and a mounting board for mounting the at least one light emitting diode on the surface thereof, the mounting board being connected to the light guide member.
