发明名称 WIRING SUBSTRATE
摘要 A wiring substrate includes a first substrate and an electronic component mounted on an upper surface of the first substrate. A first pad is formed on an uppermost wiring layer of the first substrate. A connection terminal is formed on the electronic component and is located proximate to the first pad in a plan view. The wiring substrate further includes a connection member formed on the first pad to electrically connect the first pad and the connection terminal. The connection member includes a rod-shaped core and a solder layer, which is coated around the core and joined to the first pad. The solder layer includes a bulge that spreads from the core of the connection member in a planar direction. The bulge is joined to the connection terminal of the electronic component.
