| 1. An electronic card configured to be received in a host apparatus, comprising:
a circuit board having a leading edge and a trailing edge, the leading edge being inserted into the host apparatus when the
electronic card is installed in the host apparatus, the trailing edge being opposite to the leading edge;
a semiconductor device mounted on the circuit board;
a card case covering the circuit board;
a circuit pattern provided on the circuit board;
a data pin provided on the circuit board, the data pin being adjacent to the leading edge of the circuit board;
a ground pin provided on the circuit board, the ground pin being adjacent to the leading edge of the circuit board, the ground
pin configured to be supplied with a ground potential when the electronic card is installed in the host apparatus;
a first ground conductor provided on one surface of the circuit board, the first ground conductor being electrically connected
to the ground pin; and
a first insulating material provided on the one surface of the circuit board, the first insulator material having a first
opening that exposes the first ground conductor, the first opening being adjacent to the trailing edge.
