Claim 21:
22. A light emitting module comprising:
a light guide member comprising:
an emission region defined by a sectioning groove,
a light source placement part located in the emission region, and
a light adjusting hole,
wherein, in a schematic top view, the light adjusting hole is located between the sectioning groove and the light source placement part;

a light source disposed in the light source placement part; and
a light adjusting member disposed on the light guide member, the light adjusting member being located in a region including an area immediately above the light source placement part, wherein:
the light source comprises:
a light emitting element having a lower face, an upper face located opposite to the lower face, and a lateral face extending from the lower face to the upper face,
a light transmissive member covering the upper face of the light emitting element and the lateral face of the light emitting element, and
a cover member including a light diffusing material, the cover member covering the lower face of the light emitting element and a lower face of the light transmissive member; and

in the schematic top view:
the light adjusting hole is not positioned on a first straight line connecting (i) a center of the light source and (ii) a point in the sectioning groove that is farthest from the center of the light source,
the light adjusting hole has a first lateral face located on a side closer to the light source and a second lateral face located on a side opposite the first lateral face,
the first lateral face of the light adjusting hole has a first region, and
a line normal to the first region is oblique to a second straight line connecting (i) the center of the light source and (ii) a point in the sectioning groove that is closest to the center of the light source.
