A method of manufacturing a linear light emitting device, the method comprising: providing a light transmissive member having a long side and a short side in a plan view, the providing including mounting a base material for the light transmissive member on a support and cutting the base material to obtain the light transmissive member; mounting a plurality of light emitting elements on the light transmissive member via a light transmissive adhesive, such that the light emitting elements are arranged in a row along the long side of the light transmissive member, each of the light emitting elements having a pair of electrodes (2a, 2b); forming a reflective member that covers an upper face of the support, the light transmissive member, the light transmissive adhesive, and the light emitting elements including lateral faces thereof; and grinding the reflective member from a surface opposite the light transmissive member to expose the pair of electrodes (2a, 2b) of the light emitting element, wherein the linear light emitting device has an emission face having a long side and a short side in a plan view, and a length of the short side of the light transmissive member is substantially equal to a length of the short side of the emission face of the linear light emitting device, the difference between the short-side length of the emission face of the linear light emitting device and the short-side length of the light transmissive member being within plus or minus 10% of the emission face's short-side length, and wherein the light transmissive adhesive is disposed so as to be continuous between the plurality of light emitting elements in such a manner that the light transmissive adhesive is formed so as to link a lateral face of a light emitting element and a lateral face of an adjacent light emitting element. providing a light transmissive member having a long side and a short side in a plan view, the providing including mounting a base material for the light transmissive member on a support and cutting the base material to obtain the light transmissive member; mounting a plurality of light emitting elements on the light transmissive member via a light transmissive adhesive, such that the light emitting elements are arranged in a row along the long side of the light transmissive member, each of the light emitting elements having a pair of electrodes (2a, 2b); forming a reflective member that covers an upper face of the support, the light transmissive member, the light transmissive adhesive, and the light emitting elements including lateral faces thereof; and grinding the reflective member from a surface opposite the light transmissive member to expose the pair of electrodes (2a, 2b) of the light emitting element, wherein the linear light emitting device has an emission face having a long side and a short side in a plan view, and a length of the short side of the light transmissive member is substantially equal to a length of the short side of the emission face of the linear light emitting device, the difference between the short-side length of the emission face of the linear light emitting device and the short-side length of the light transmissive member being within plus or minus 10% of the emission face's short-side length, and wherein the light transmissive adhesive is disposed so as to be continuous between the plurality of light emitting elements in such a manner that the light transmissive adhesive is formed so as to link a lateral face of a light emitting element and a lateral face of an adjacent light emitting element.
