Side terminals 3 at respective corners of a package are higher than side terminals 4 on each side of the package. Thus, even if the side terminals 4 on each side are lower than those according to the conventional art owing to miniaturization or the like, when a device is mounted on a mounting substrate by soldering, a solder fillet 11 of a sufficient size can be formed between each of the corner side terminals 3, which significantly affect reliability, and a corresponding terminal on the mounting substrate. Thus, the device can be more reliably mounted on the mounting substrate by soldering.
