Semiconductor storage device

A semiconductor storage device comprising:

• an insulating base material;
• a wiring pattern on the insulating base material;
• an insulating film on a surface of the insulating base material, the insulating film covering a part of the wiring pattern;
• and
• an electronic component electrically connected to the wiring pattern,
• wherein the wiring pattern includes a first pad having an edge formed in an arc shape, and a first wire,
• the insulating film has a first opening larger than the first pad,
• the first wire has a first portion, a second portion, and a third portion,
• the first portion being connected to the first pad inside the first opening and the first portion extending in a first direction,
• the second portion being connected to the first pad inside the first opening and the second portion extending in a second direction, the second portion has a first distance from the first portion and a second distance from the first pad,
• the first distance increases as the second distance increases, and
• the third portion being in a side opposite to the first pad with respect to the first portion and the second portion, the third portion being connected to the first portion and the second portion, and
• the first wire is connected with the first pad in an angular range of not more than 90 degrees in a circumferential direction of the first pad.
