Electrical component with contact terminal portions are disposed in a generally trapezoidal shape

to be mounted in a connector which is adapted to a connection object to connect to a mating connector, the connector includes contacts (14, 15), each of which has a contact portion on a contact portion of the connector for the connection to the associated connector is disposed, and a terminal portion (14a, 15a) which is arranged on a connection portion side for connection with the connection object. The contacts have a plurality of signal contact members (14) and a plurality of ground contact members (15). The signal contact members form a plurality of pairs. The ground contact members are arranged at intervals. On the contact portion side of the pairs of signal contact members are respectively disposed in the spaces. On the connection portion side of the signal contact members and ground contact members are separately disposed on parallel rows and the pairs of signal contact members are respectively opposite in the rooms.
