To provide a strain gauge having a resistor formed on a flexible substrate, in which an electrode structure is realized with which, even when downsized, it is possible to secure the reliability of joint with an object to be joined.SOLUTION: This strain gauge comprises a flexible substrate, a resistor formed from a material containing at least either chromium or nickel, and a pair of electrodes electrically connected to the resistor on the substrate. Each of the electrodes include a plurality of first patterns juxtaposed at a prescribed interval and electrically connected to each other, with a plurality of second patterns directed in the same longitudinal direction as the plurality of first patterns arranged between the electrodes facing each other.SELECTED DRAWING: Figure 1 【課題】可撓性を有する基材上に形成された抵抗体を有するひずみゲージにおいて、小型化しても被接合物との接合信頼性を確保できる電極構造を実現する。【解決手段】本ひずみゲージは、可撓性を有する基材と、前記基材上に、クロムとニッケルの少なくとも一方を含む材料から形成された抵抗体と、前記抵抗体と電気的に接続された一対の電極と、を有し、各々の前記電極は、所定の間隔で並置され互いに電気的に接続された複数の第１パターンを含み、対向する前記電極の間には、複数の前記第１パターンと長手方向を同一方向に向けた複数の第２パターンが配置されている。【選択図】図１
