Abstract
A light emitting device includes first and second semiconductor laser elements, a base, a surrounding part, a wavelength converting member, and first and second wiring parts. The first laser element, the converting member and the second laser element are arranged in order in a first direction. At least one of the first and second laser elements is disposed between the first and second wiring parts in a second direction perpendicular to the first direction. An outermost periphery of the converting member is between a first imaginary line and a second imaginary line in the top view. The first and second imaginary lines are both parallel to the second direction. The first imaginary line passes through an outermost periphery in the first direction of the second laser element and the second imaginary line passes through an outermost periphery in a direction opposite to the first direction of the first laser element.
