PROBLEM TO BE SOLVED: To provide a power line communication module in which cost reduction and reduction in size can be attained by preventing interference between a communication signal of a route A (a communication path between an electric power company and the power line communication module) and a communication signal of a route B (a communication path between the electric power line communication module and a user).SOLUTION: A power line communication module A which performs power line communication via a power line W1 for supplying commercial power to a user comprises: a filter 2 which is interposed in the power line W1; and a microcomputer 1 which is connected to a trunk-side power line W1a connected to a primary side of the filter 2 to be a power supply path from a commercial power source to the filter 2 and connected to a user-side power line W1b connected to a secondary side of the filter 2 to be a power supply path to equipment of the user, and which performs power line communication via the trunk-side power line W1a and the user-side power line W1b. The filter 2 attenuates a frequency component of a communication signal used for power line communication, and the microcomputer 1 is constituted of an integrated circuit of one chip. |
