摘要： An FEC coder in a transmission device according to an exemplary embodiment of the present disclosure performs BCH coding and LDPC coding based on whether a code length of the LDPC coding is a 16 k mode or a 64 k mode. A mapper performs mapping in an I-Q coordinate to perform conversion into an FEC block, and outputs pieces of mapping data (cells). The mapper defines different non-uniform mapping patterns with respect to different code lengths even an identical coding rate is used by the FEC coder. This configuration improves a shaping gain for different error correction code lengths in a transmission technology in which modulation of the non-uniform mapping pattern is used.

The insulating plate is disposed between the electrode group and the sealing body and has a disk shape with a thickness T of 0.1 mm or more. The insulating plate has a first hole formed centrally therein and at least one second hole formed around the first hole so as to extend along the outer periphery of the disk shape. The ratio (=T/D) of the thickness T to a diameter D of the insulating plate is 0.016 or less, and the insulating plate has an opening ratio of 36% or less.
