A signal divider 1 can be miniaturized in which divided signals do not interfere with each other and, at the same time, DC power does not creep into each other. Since a signal dividing circuit 11 is a lumped constant circuit and each element can be made as a chip element, the signal divider 1 can be miniaturized. A division ratio of divided signal output from a first division output terminal OUT 1 and a second division output terminal OUT 2 can be set by a circuit A and a circuit B. Since a circuit C is connected in parallel with a series circuit composed of the circuit A and the circuit B to produce resonance at a usage frequency, a sufficient amount of isolation between the first division output terminal OUT 1 and the second division output terminal OUT 2 can be guaranteed. DC power supplied from the first division output terminal OUT 1 and the second division output terminal OUT 2 can be prevented from creeping out by the capacitors C 2 , C 4.
