PROBLEM TO BE SOLVED: To obtain: a Wilkinson divider capable of being reduced in size, reduced in insertion loss, and stabilized in high frequency characteristics; and a high frequency circuit.SOLUTION: A Wilkinson divider includes: a transmission line 14a connected between an external circuit connection terminal 11 and an output terminal 25a and having a length of a 1/4 wavelength; a transmission line 14b connected between the external circuit connection terminal 11 and an output terminal 25b and having a length of a 1/4 wavelength; and a resistor 23 connected between the output terminal 25a and the output terminal 25b. The resistor 23 is formed in an integrated circuit 1, and the transmission lines 14a, 14b are formed in a rewiring layer 4. 【課題】サイズの小形化、挿入損失の低減化及び高周波特性の安定化を図ることができるウィルキンソン型分配器及び高周波回路を得ることを目的とする。【解決手段】外部回路接続端子１１と出力端子２５ａの間に接続される４分の１波長の長さを有する伝送線路１４ａと、外部回路接続端子１１と出力端子２５ｂの間に接続される４分の１波長の長さを有する伝送線路１４ｂと、出力端子２５ａと出力端子２５ｂの間に接続される抵抗体２３とを備え、抵抗体２３が集積回路１に形成され、伝送線路１４ａ，１４ｂが再配線層４に形成されるように構成する。【選択図】図１
