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.

A method of anchoring a connector in a first object, wherein the first object is a lightweight building element having a first outer building layer and an interlining layer, and wherein the connector includes thermoplastic material in a solid state. The method includes: bringing a coupling surface portion of the connector into contact with an attachment location of the first outer building layer; displacing a portion of the first outer building layer at the attachment location with respect to the interlining layer by applying a first pressing force to the first outer building layer and thereby piercing the first outer building layer; applying a second pressing force to the connector and transferring energy to the connector until a flow portion of the thermoplastic material has liquefied and flown to interpenetrate structures of the interlining layer; and stopping the energy transfer and allowing the flow portion to re-solidify.
