Claim 6:
7. An optical connection member comprising:
a first lens plate
disposed on an end face of a first ferrule that holds end parts of multi-core fibers, and
comprising first lenses corresponding to the multi-core fibers;

a second lens plate
disposed on an end face of a second ferrule that holds end parts of single-core fibers, and
comprising second lenses corresponding to the single-core fibers; and

a relay plate
disposed between the first lens plate and the second lens plate, and
that propagates an optical signal between the first lenses and the second lenses, wherein

a pair of through holes are formed in each of the first lens plate, the second lens plate, and the relay plate,
the first lens plate, the second lens plate, and the relay plate are aligned with respect to the first ferrule and the second ferrule by fitting guide pins in the through holes,
the relay plate comprises:
first optical elements corresponding to the first lenses; and
second optical elements corresponding to the second lenses,

the relay plate propagates an optical signal between the first optical elements and the second optical elements,
the first optical elements face a corresponding first lens such that collimated light propagates between the respective first lenses and the corresponding first optical elements, and
the second optical elements face a corresponding second lens such that collimated light propagates between the respective second lenses and the corresponding second optical elements.
