Zusammenfassung:	A diplexer provides a high degree of design freedom for satisfying the requirements of electric characteristics so as to realize desired characteristics and at the same time can be downsized and a multiplexer is realized by using such a diplexer. The diplexer includes a filter (30) having a first pass band and a filter (20) having a second pass band with a frequency band at least twice as high as the frequency band of the first pass band, the filter (30) having the first pass band being a filter of the lumped constant type, the filter (20) having the second pass band being a filter of the distributed constant type.
