Abstract: A light-emitting module includes: a light-emitting device; and a base that is electroconductive, the base including: a mounting surface that faces a first direction and on which the light-emitting device is mounted with a bonding material, and at least one protrusion that is adjacent to the mounting surface in a direction intersecting the first direction and protrudes in the first direction with respect to the mounting surface. The at least one protrusion includes a plurality of first surfaces that are in contact with the light-emitting device. The light-emitting device includes a light-emitting element and has a side surface at which an electroconductive part electrically connected to an electrode of the light-emitting element is exposed. The side surface is partially in contact with the first surfaces, and a part of the side surface at which the electroconductive part is exposed is not in contact with the first surfaces.
