Claim 0:
1. A holding device comprising:
a plate-shaped member having an approximately flat first surface approximately orthogonal to a first direction and a second surface opposite to the first surface;
a base member having a third surface and a fourth surface opposite to the third surface, the base member being disposed such that the third surface faces the second surface of the plate-shaped member, the base member having a plurality of first through holes extending from the third surface to the fourth surface;
a plurality of heating elements disposed in the plate-shaped member;
a plurality of electricity supply terminals electrically connected to the respective heating elements;
a bonding portion disposed between the second surface of the plate-shaped member and the third surface of the base member to bond the plate-shaped member and the base member together, the bonding portion having a plurality of second through holes which communicate with the respective first through holes of the base member and form, in cooperation with the first through holes, terminal holes for receiving the electricity supply terminals; and
insulating members received in the respective terminal holes,
the holding device holding an object on the first surface of the plate-shaped member, wherein
the plurality of electricity supply terminals include N individual electricity supply terminals (N is an integer of 2 or more) electrically connected to respective N heating elements of the plurality of heating elements, and a common electricity supply terminal electrically connected to all the N heating elements;
the N individual electricity supply terminals are received in a first one of the terminal holes and are insulated from one another by one of the insulating members, the first one of the terminal holes not receiving the common electricity supply terminal; and
the common electricity supply terminal is received in a second one of the terminal holes, the second one of the terminal holes not receiving the individual electricity supply terminals.
