Abstract
A resin-junction body includes a first resin member, a second resin member including a concave portion and laminated on the first resin member so as to contact the first resin member at a contact surface. The concave portion comprises a bottom face on a first resin member side. The resin-junction body further includes a joining layer that joins the first resin member and the second resin member and that extends from the bottom face towards the first resin member.

A resin-junction body comprising:
- a first resin member formed by thermoplastic-resin material;
- a second resin member comprising a hole and formed by thermoplastic-resin material;
- and
- an entirety of a third resin member disposed inside the hole and formed by thermoplastic-resin material,
- wherein optical transparency of the third resin member is higher than optical transparency of the first resin member and the second resin member,
- wherein the first resin member, the second resin member, and the third resin member are joined by being welded at a welding region,
- wherein the welding region extends from the hole towards the first resin member,
- wherein the hole comprises an inner side wall that contacts the third resin member, and
- wherein the welding region extends along the inner side wall in a direction vertical to the first resin member.
