A semiconductor device, including an electrically conductive portion, and a terminal. The terminal includes a bonding portion that is of a flat plate shape and has: a rear surface bonded to the electrically conductive portion, and a front surface having an indentation formed thereon. The front surface has two opposite sides that are respectively a bonding front-end side and a bonding rear-end side. The indentation has two opposite sides that are respectively an indentation front-end side and an indentation rear-end side. The indentation front-end side is flush with the bonding front-end side. A length of the indentation rear-end side is shorter than a length of the bonding rear-end side.
