Disclosed are an encoding device and a decoding device which can effectively reduce the decoding failure frequency in LDPC encoding/decoding. A loss correction encoding device (120) includes a padding unit (121) which adds a padding packet to an information packet sequence; an interleave unit (122) which rearranges the padding packet and the information packet; and a loss correction encoding unit (123) which performs loss correction encoding for the packet string after the interleave. The interleave unit (122) rearranges the padding packet and the information packet according to variable nodes constituting a minimum stopping set of the inspection matrix which defines a low-density parity inspection code. The interleave unit (122) uses such a rearrangement pattern that avoids a loss correction failure by the minimum stopping set of the LDPC inspection matrix so as to reduce the probability of the loss correction failure by the minimum stopping set.
