Semiconductor laser element

A semiconductor laser element, comprising:

• an element body including an element front surface and an element back surface that face away from each other, the element front surface facing in a thickness direction, a first end surface and a second end surface that face away from each other in a first direction as viewed in the thickness direction, and a first side surface and a second side surface that face away from each other in a second direction orthogonal to the first direction as viewed in the thickness direction, the element body being configured to emit laser light from the first end surface;
• a front electrode formed on the element front surface;
• and
• a back electrode formed on the element back surface, wherein
• the element body includes
• a first recess recessed into the element body between the first side surface and the element front surface, and
• a second recess recessed into the element body between the second side surface and the element front surface,
• the first recess includes a first inner side surface facing in the same direction as the first side surface and a first connection surface connecting the first inner side surface and the first side surface,
• the second recess includes a second inner side surface facing in the same direction as the second side surface and a second connection surface connecting the second inner side surface and the second side surface, and
• the first connection surface and the second connection surface each include an inclined surface inclined relative to the element front surface at an angle differing from those of the first side surface and the second side surface.
