Wiring circuit board

A wiring circuit board comprising:

• a first insulating layer;
• a wiring layer disposed on one side in a thickness direction of the first insulating layer;
• a second insulating layer disposed on one side in the thickness direction of the first insulating layer so as to cover the wiring layer;
• a pad portion disposed on one side in the thickness direction of the second insulating layer;
• and
• a conductive connection portion electrically connecting the wiring layer to the pad portion, wherein
• the second insulating layer has a through opening portion penetrating the second insulating layer in the thickness direction and having an opening along at least a part of a peripheral end portion of the pad portion;
• the wiring layer has a contact portion facing the through opening portion;
• the conductive connection portion is disposed in the through opening portion, is connected to at least the part of the peripheral end portion of the pad portion, and is connected to the contact portion of the wiring layer;
• the through opening portion has an inner peripheral surface having a first opening end on one side in the thickness direction and a second opening end on the other side in the thickness direction;
• the inner peripheral surface of the through opening portion has a tapered shape which is inclined outwardly from the second opening end toward the first opening end;
• the second insulating layer includes a land portion surrounded by the through opening portion;
• and
• the land portion has a peripheral side surface having a tapered shape which is inclined inwardly from an other-side end portion toward a one-side end portion.
