A sewing machine, comprising:
- a thread cutter including:
- a cutter blade having a blade edge configured to cut a thread;
- and
- a movable member including a guide having a guide surface adjacent to the cutter blade, the guide being configured to receive force from the thread at the guide surface during the course of cutting the thread with the cutter blade by slidably moving the thread in a longitudinal direction of the blade edge and to move in a moving direction which is the longitudinal direction of the blade edge,
- wherein the movable member includes a wire having elasticity and the guide is configured to move in the moving direction by being elastically deformed by the force received from the thread.
