Light emitting device

A light emitting device comprising:

• a base having an upper surface;
• a frame defining a through-opening and fixed to the upper surface of the base;
• one or more semiconductor laser elements fixed to the upper surface of the base inward of the frame;
• a cover member fixed to the upper surface of the frame so as to cover the through-opening of the frame, the cover member being configured to allow light from the one or more semiconductor laser elements to pass through the cover member;
• an optical member fixed to the cover member via an adhesive member, the optical member being configured to allow light that has passed through the cover member to pass through the optical member;
• a pressing member pressing the optical member to the frame;
• wherein the cover member includes an upper surface located above the upper surface of the frame, a first inner lateral surface extended downward from the upper surface inward of the frame, and a first upward-facing surface extending inward from the first inner lateral surface;
• the adhesive member includes:
• one or more first adhesive portions disposed between the upper surface of the cover member and the lower surface of the optical member, and
• two or more second adhesive portions respectively disposed at locations in contact with or spaced apart from the one or more first adhesive portions when viewed from above, in contact with the first inner lateral surface of the cover member and with the lateral surface of the optical member.
