The present invention belongs to the technical field of intraoral scanners. Disclosed are a scanning head with a reinforced adhesive-bonding structure, and an intraoral scanner with increased repeated use times and having the scanning head. The scanning head comprises a plastic base layer (10), a window being formed at a tip thereof; an adhesive-bonding layer (20), which is coated on an entire or partial surface of a plastic base layer area facing the window; and a reflecting-mirror layer (30), which is arranged in the window and is adhered to the plastic base layer (10) by means of the adhesive-bonding layer (20). The adhesive-bonding layer (20) is configured to enhance an embedding force with the plastic base layer (10) by means of a reinforcing structure, so as to be strongly adhered to the reflecting-mirror layer (30). By means of improving surface energy of a plastic at a bonding site, or by means of grafting a material with a relatively high surface energy at a contact surface in an external embedding m
