Abstract
An electronic device including a first electronic component, a sealing resin, and a first lead including an inner portion and an outer portion. The inner portion includes a die pad on which the first electronic component is mounted, and a connecting portion connecting the outer portion and the die pad. The outer portion is located on one side in a first direction, with respect to the die pad. The center of the outer portion is located on one side of the center of the die pad, in a second direction. As viewed in a thickness direction, the distance from a first end of a first cutting mark of the outer portion, in the first direction, to a first corner portion of the die pad, is 10.8 times or less, of a first length of the outer portion in the second direction.

An electronic device comprising:
- a first electronic component;
- a sealing resin covering the first electronic component;
- and
- a first lead including a first inner portion covered with the sealing resin, and a first outer portion exposed from the sealing resin,
- wherein the first inner portion includes a first die pad on which the first electronic component is mounted, and a first connecting portion connecting the first outer portion and the first die pad,
- the first outer portion is located on one side in a first direction with respect to the first die pad, the first direction being orthogonal to a thickness direction of the first electronic component,
- a center of the first outer portion is, in a second direction orthogonal to the thickness direction and the first direction, located at a same position as a center of the first die pad, or on one side of the center of the first die pad in the second direction,
- the first die pad has a rectangular shape as viewed in the thickness direction, and includes a first corner portion located on an other side in the first direction, and on an other side in the second direction,
- the first outer portion includes a first cutting mark oriented to the other side in the second direction, and
- a first distance from a first end of the first cutting mark on the other side in the first direction, to the first corner portion is, as viewed in the thickness direction, equal to or shorter than 10.8 times as long as a first length of the first outer portion in the second direction.
