Patent abstract
A lead frame is buried in mold resin to form a mold structure. A wide blade is used to make an indentation having an alignment step in the mold structure. Then, a narrow blade is used to split the mold structure. At the outer perimeter portion of a base which is a separate part separated from the mold structure, an alignment step is formed. Due to the alignment step, an optical element, such as a mirror tube of an imaging optical system, or the like, is readily and quickly attached.
