PROBLEM TO BE SOLVED: To provide a bonding structure for optical component which can prevent optical adverse influence and breaking from occurring by reducing stress caused in the optical component due to thermal expansion or thermal contraction. SOLUTION: In the bonding structure for optical component with which the optical component 2 is bonded to an object 4 to be bonded having a different thermal expansion coefficient from the optical component 2, a hollow part 12 is provided on either the adhesion surface 2a of the optical component or the adhesion surface 4a of the object 4, and the hollow part 12 is formed so that its bottom surface is in a planar shape and its periphery side surface continuing to the bottom surface is larger than the diameter of a bottom part toward an opening side. A projection part 14 to be fit in the hollow part 12 is provided through an adhesive 6 on the other adhesion surface. Thus, the optical adverse influence and the breaking are prevented by reducing the stress caused in the optical component due to the thermal expansion or the thermal contraction.
