Preferably, the support element and the deflection element are integrally formed and the support element and the further support element are not integrally formed. Preferably, both the support element and the further support element are designed as rod-type torsion springs. Preferably, the support element and the further support element are interconnected by bonding at their respective contact surfaces in an end region facing the fixed structure. The invention further relates to a method for producing a scanning unit.
