This sewing machine is characterized by being provided with: a hook having a hook point which catches a loop of a needle thread formed by movement of a sewing needle inserted through a to-be-sewn article, from a bottom dead center to a top dead center; a rotation information detector (302) which detects rotation information about a motor which rotates the hook; and a monitoring unit (503) which monitors generation of stitch skipping on the basis of the rotation information detected during a time period in which the hook point of the hook catches the needle thread, and outputs a stitch skippingdetection signal when the stitch skipping is detected. The present invention exerts an advantageous effect of being able to detect generation of stitch skipping with a simple configuration requiringfew additional components.
