In a light guide pointer, a vertex portion of a light control space is located on a sub-pointer portion side with respect to a center axis of a light entrance shaft, providing appropriate luminance balance between a main pointer portion and the sub-pointer portion. The light control space includes a circular arc portion, thereby broadening diffusion range of light that has passed through the light control space and preventing attenuation of light traveling along inclined portions. A center of the circular arc portion is located on the main pointer portion side with respect to the center axis, allowing strong light that has entered the light control space from the vertex portion to be diffused more. Local focusing and/or attenuation of light can be prevented, while providing appropriate luminance balance between the main pointer portion side and the sub-pointer portion side, thereby reducing luminance unevenness at the light emitting face.
