An object of the present invention is to provide an optical transmission structural body capable of preferably transmitting an optical signal between an optical wiring and an optical waveguide irrespective of a shape of a portion of the optical wiring, the portion being connected to a core part of the optical waveguide. The extra ECC encoder includes: an extra parity generator generating an extra ECC data block based on data that is to be recorded on the information recording medium, performing ECC on the extra ECC data block, and generating at least one extra parity. The base-region low-resistance metal silicide layer extends all the way to the outside of the emitter-base spacer dielectric region. On determining that a command signal is a re-transmitted command signal, the remote transponder re-transmits the response signal as an UHF response signal URs. Representative pixel values for the respective acquired regions are acquired based on the illuminance component image. The pulp products can be advantageously incorporated into absorbent articles and can optionally further include superabsorbent material.
