PROBLEM TO BE SOLVED: To provide a signal transmission circuit that mitigates the drop of characteristic impedance caused by a capacitive element for an electrostatic countermeasure. SOLUTION: A signal transmission circuit 1 comprises a common mode filter 12, a first capacitive element 13, and a second capacitive element 14. A first input 121 and a second input 122 of the common mode filter 12 are applied with signals having phases opposite to each other. The first output 123 of the common mode filter 12 is connected to the first input terminal 131 of the first capacitive element 13. The second output 124 of the common mode filter 12 is connected to the second input terminal 141 of the second capacitive element 14. The length d of a first connection 15 that connects the first output 123 to the first input terminal 131, and the length d of a second connection 15 that connects the second output 124 to the second input terminal 141 are 3mm or less, respectively.
