Light-emitting module

A light-emitting module comprising:

• a light-emitting device including a plurality of semiconductor laser elements and a substrate on which the plurality of semiconductor laser elements are arranged along a longitudinal direction of the substrate;
• and
• a wiring board having a mounting surface including a first area on which the light-emitting device is mounted, the wiring board having a longitudinal direction extending in a first direction and a widthwise direction extending in a second direction perpendicular to the first direction in a top view that is viewed from a direction perpendicular to the mounting surface, wherein
• the wiring board includes
• a first fixing portion and a second fixing portion at which the wiring board is configured to be fixed in place,
• a first electrode portion to which the substrate is joined for electrical connection to the plurality of semiconductor laser elements, and
• a second electrode portion electrically connected to the first electrode portion, the second electrode portion being configured to be connected to a connecting member for electrical connection of the light-emitting device to an external device,
• in the top view,
• the first area is located between the first fixing portion and the second fixing portion,
• the second fixing portion is disposed between the first electrode portion and the second electrode portion, and
• the substrate has the longitudinal direction extending in the first direction and a widthwise direction extending in the second direction.
