1. 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;
a first light transmissive member comprising a light transmissive resin material, the first light transmissive member being provided in the light source placement part so as to embed the light source; and
a first light adjusting member disposed on the light guide member, the first 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 first face, a second face located opposite to the first face, and a third face extending from the first face to the second face,
a second light transmissive member covering the second face of the light emitting element and the third face of the light emitting element,
a cover member including a light diffusing material, the cover member covering the first face of the light emitting element and a lower face of the second light transmissive member, and
a second light adjusting member including a light reflecting material, the second light adjusting member being disposed on the second 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 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.
