A substrate fixing device includes a baseplate, an electrostatic attraction member, and an electrode pin. The baseplate includes a metallic member in which a through hole is famed. The electrostatic attraction member is over a surface of the baseplate and includes an attraction electrode. The electrode pin is inserted through the through hole to be connected to the attraction electrode. A recess communicating with the through hole is formed in the surface of the metallic member with the through hole being within the recess in a plan view from a direction perpendicular to the surface of the metallic member.
