A narrow-pitch connector; a pitch converter; a micro-machine; a piezoelectric actuator; an electrostatic actuator; an ink jet head; an ink jet printer; a liquid crystal device; and electronic equipment in which the positional deviation between terminal electrodes to be connected with each other can be reduced even if thermal stress is applied, and in which effective heat radiation from a semiconductor device mounted thereon can be achieved. A plurality of first terminal electrodes (30) and a plurality of second terminal electrodes (32) are formed on a substrate. First wiring (24A) connected with the first terminal electrodes (30) and second wiring (24B) connected with the second terminal electrodes (32) are formed. A semiconductor device (33), which is electrically connected with the first wiring (24A) and the second wiring (24B), is provided. The pitch among the first terminal electrodes is set to be narrower than the pitch among the second terminal electrodes, and the number of the first terminal electrodes is set to be larger than the number of the second terminal electrodes.
