A lead frame comprising:
- a plurality of units connected together, each of the units including
- a first lead portion and a second lead portion spaced apart from and opposite to each other, the first and second lead portions being configured to mount a semiconductor element and to be electrically connected to a pair of electrodes of the semiconductor element,
- the first lead portion including first, second, and third extended portions respectively extending from the first lead portion along a first direction, and
- the second lead portion including fourth fifth and sixth extended portions respectively extending from the second lead portion along a second direction different from the first direction;
- wherein the first and second extended portions of the first lead portion are arranged to surround a tip portion of the fourth extended portion of the second lead portion on one side respective to a center line of the unit, and the fifth and sixth extended portions of the second lead portion are arranged to surround a tip portion of the third extended portion of the first lead portion on the other side respective to the center line of the unit.
