1. An electronic control device comprising:
a housing having conductivity;
a circuit board that is arranged in the housing and has a first electronic component mounted on a mounting surface;
an external connection portion that is electrically connected to the circuit board and is connectable to a device outside the housing; and
a duplexing member that has conductivity and is arranged between an inner surface of the housing and the mounting surface of the circuit board, wherein the duplexing member is (i) connected to a first portion of the housing through the circuit board and at least one connection structure that is electrically conductive or capacitive, and (ii) the duplexing member is also connected to a second portion of the housing opposite to the first portion,
wherein the duplexing member forms a cutout portion to avoid contact between the duplexing member and the first electronic component, and further forms a partition portion that partitions the external connection portion between the housing and the circuit board.
