Terminal tabs are provided on each of the arms, the first and third tabs on the first and third arms extending parallel to each other towards the other carrier strip and the tab on the second arm extending parallel to the other tabs and towards the one carrier strip. Each lead frame is secured to the one carrier strip by a connection section extending from the second tab. The chip support portion and the first and third arms are additionally supported by a removable support member extending from the other carrier strip.
