Strain gauge

A strain gauge comprising:

• a flexible substrate;
• a resistor formed of material containing at least one from among chromium and nickel, on or above the substrate;
• and
• a pair of electrodes electrically connected to the resistor,
• wherein each electrode includes a plurality of first patterns that are juxtaposed at predetermined intervals and that are electrically connected to each other,
• wherein a plurality of second patterns of which longitudinal directions are toward a same direction as a longitudinal direction of each of the first patterns are disposed between opposing electrodes,
• wherein the plurality of second patterns are a zigzag pattern that constitutes the resistor, and
• wherein the plurality of second patterns of which the longitudinal directions are toward a same direction as the longitudinal direction of each first pattern are disposed, the second patterns being interposed between first patterns opposite each other, among the first patterns, and the first patterns opposite each other being from among given first patterns that constitute one of the electrodes and given first patterns that constitute another electrode.

• wherein a width of each first pattern is same as a width of each second pattern,
• wherein a space between first patterns that are next to each other is same as a space between second patterns that are next to each other, and
• wherein the plurality of second patterns of which the longitudinal directions are toward a same direction as the longitudinal direction of each first pattern are disposed, each of the second patterns being interposed between end portions of opposing first patterns, among the first patterns, the opposing first patterns being from among given first patterns that constitute one of the electrodes and given first patterns that constitute another electrode.
