Industrial robot

An industrial robot, comprising:

• a hand on which a conveying target formed to have a thin plate shape is to be loaded, and an arm that supports the hand;
• wherein
• the hand comprises a connecting portion that configures a base end portion of the hand and is connected to the arm, a tip end portion of the hand on which the conveying target is to be loaded being connected to a tip end portion of the connecting portion, and a plurality of sensing mechanisms that sense the conveying target for correcting a position of the hand,
• the hand is equipped with a bracket fixed to the tip end portion of the connecting portion, a tip end side of the bracket being formed in an arc shape when being viewed in an up-down direction,
• a part of a region of the bracket overlaps a part of a region of the tip end portion of the hand when being viewed in the up-down direction,
• the sensing mechanisms comprises four transmission type optical sensors, the four transmission type optical sensors being fixed to the tip end side of the bracket, and
• two of the four transmission type optical sensors are positioned on one side of a base end part of the tip end portion of the hand in an orthogonal direction and the other two of the four transmission type optical sensors are positioned on the other side of the base end part of the tip end portion of the hand in the orthogonal direction, so that the four transmission type optical sensors are aligned in an arc along an outer peripheral surface of the conveying target when the conveying target is loaded at a correct position on the hand, the orthogonal direction being a direction orthogonal to a longitudinal direction of the hand.
