Light emitting apparatus and optical apparatus

A light emitting apparatus comprising:

• a first holder configured to hold a light source and including a first contact surface;
• a second holder configured to hold an optical element that condenses light from the light source, and including:
• a first screw portion whose axis extends along an optical axis direction of an optical axis of the optical element;
• and
• a second screw portion whose axis also extends along the optical axis direction;
• a first screw member configured to be screwed to the first screw portion of the second holder to hold the optical element relative to the second holder;
• and
• a second screw member screwed to the second screw portion of the second holder to secure the first holder to the second holder, and including a second contact surface,
• wherein the first contact surface includes a first recess located outside the first screw member in a direction perpendicular to the optical axis direction, and
• wherein an adhesive adhering the second screw member and the first holder to each other is disposed in the first recess, and
• wherein the first and second contact surfaces, other than at the first recess, are:
• in direct contact with each other;
• extend in the direction perpendicular to the optical axis direction;
• and
• confront each other in the optical axis direction.
