1. A canceler device comprising:
a line connector having a first terminal, a second terminal, and a third terminal, the line connector being configured to output a signal provided to the first terminal to the second terminal; and
a reflection circuit to output a reflected wave of the signal output to the second terminal to the third terminal,
wherein the reflection circuit includes:
a first variable resistor having a first end connected to the second terminal; and
a second variable resistor having a first end connected to the second terminal and a second end grounded; and
a resonance circuit having a first end connected to a second end of the first variable resistor and a second end grounded.
