Abstract
To improve the reliability of light-emitting devices and light-emitting modules. [Solution] The light-emitting device comprises a plurality of light sources arranged in a first direction, each having a semiconductor structure and a first electrode and a second electrode disposed on the lower surface of the semiconductor structure; a covering member that integrally holds the plurality of light sources; a plurality of first conductive members that are joined to the first electrode of each of the plurality of light sources and connected to a third conductive member that is connected to a fifth conductive member outside the light source; a plurality of second conductive members that are joined to the second electrode and connected to a fourth conductive member that is connected to a sixth conductive member outside the light source; and an insulating layer located between the fifth conductive member and the sixth conductive member in a first direction, wherein the width of the insulating layer in a first direction is shorter than the distance between the fifth conductive member and the sixth conductive member in a first direction, and part or all of the insulating layer is located between the first conductive member and the second conductive member that are joined to the first electrode and the second electrode of each of the light sources, respectively.
