Patent ID: 7268416

Claim:
A mounting structure comprising: a mounting substrate includes; a conductive pattern formed over the mounting substrate and extending in a Y direction, the conductive pattern having mounting pads arranged in an X direction, the X direction and the Y direction being two directions orthogonal to each other; and a mounted member mounted on the mounting substrate so as to be electrically connected to the mounting pads, wherein a first conductive layer, an insulating layer, a second conductive layer, and a third conductive layer are formed on the mounting substrate in this order from a lower side to an upper side of the mounting substrate, and each conductive pattern includes: the mounting pad formed by stacking the first conductive layer, the insulating layer, and the third conductive layer, which is an outermost layer, in this order; a test pad that is positioned adjacent to a region where the mounting pad is formed, outside a region where the mounted member is mounted, and formed by stacking the first conductive layer, the insulating layer, and the third conductive layer, which is the outermost layer, in this order; and a lead portion that extends from the test pad and formed by stacking the first conductive layer and the insulating layer, which is an outermost layer.
