Abstract
According to the present disclosure, a strain gauge has: a flexible substrate; a resistor formed on the substrate; and a pair of electrodes formed on the substrate and electrically connected with the resistor via conductive traces, and, in this strain gauge, the conductive traces include a first metal layer and a second metal layer formed over an upper surface of the first metal layer, and the second metal layer is formed in a pattern that is different from a pattern of the first metal layer.
