Abstract:
An optical element includes a first substrate having a first surface, a resin member disposed on the first surface, and a second substrate disposed above the resin member with a joining member interposed therebetween. The resin member has a first region contacting the joining member and a second region surrounding the first region and not contacting the joining member. An inclined portion having a thickness increasing from a starting point located in the second region toward an outer circumference of the resin member, is disposed in the second region. A tangent of the first surface, orthogonal to a normal of the first surface passing through the starting point, and a straight line passing through the starting point and a point at which the inclined portion has a largest thickness, form an angle of 25° or more and 45° or less.
