Abstract: PROBLEM TO BE SOLVED: To provide a communication apparatus that is hardly affected by an unnecessary electromagnetic onto a balance/unbalance converter. SOLUTION: The communication apparatus has a push-pull circuit 16, balance/unbalance converters 13a, 13b connected to its input and output, and the balance/unbalance converters 13a, 13b are formed to be L-shape. Since the size of the balance/unbalance converters 13a, 13b in its length direction with respect to the sensitivity direction of an unnecessary electromagnetic wave can be decreased, the resonance frequency of the balance/unbalance converters 13a, 13b is shifted toward high frequencies. Thus, the frequency of a interference wave is shifted toward higher frequencies than a substantial objective signal frequency.
