PROBLEM TO BE SOLVED: To obtain an even number harmonic mixer, an orthogonal mixer and an image rejection mixer that can be miniaturized without incurring increase in current consumption. SOLUTION: In the mixer, there is provided an RF/LO block circuit 21 which blocks passing of RF and LO signals that permits passing of an IF signal outputted from a connecting point 14 of mixer diodes 12, 13 and with an RF/LO block circuit 23 that blocks passing of the RF and LO signals that permits passing of an IF signal outputted from a connecting point 15 of the mixer diodes 12, 13.
