1. An electromagnetic relay, comprising:
a first fixed terminal including a first fixed contact;
a second fixed terminal including a second fixed contact;
a movable contact piece including a first movable contact disposed to face the first fixed contact and a second movable contact disposed to face the second fixed contact, the movable contact piece being movable in a movement direction including a first direction from the first movable contact toward the first fixed contact and a second direction from the first fixed contact toward the first movable contact;
a drive shaft including a shaft portion extending in the movement direction and a flange portion projecting from the shaft portion, the drive shaft being spaced apart from the movable contact piece in the second direction;
a spacer disposed between the movable contact piece and the drive shaft;
a contact spring disposed between the spacer and the drive shaft, the contact spring configured to urge the spacer and the drive shaft away from each other in the movement direction;
a stopper connected to the spacer, the stopper including a holding portion and a press portion, the holding portion configured to hold, together with the spacer, the movable contact piece in the movement direction, the press portion configured to be pressed in the second direction by the flange portion of the drive shaft in a state where the first movable contact is separated from the first fixed contact; and
a driving device configured to move the drive shaft in the movement direction.
