1. A heater for heating an object to be heated in such a manner that the object to be heated is swept with the heater disposed opposite the object to be heated,
the heater comprising:
a base having a rectangular shape; and
a plurality of heating cells each independently receiving power supply,
the heating cells being disposed on the base and arranged in a longitudinal direction of the base,
wherein
each of the heating cells includes a plurality of lateral wires extending in substantially parallel with the longitudinal direction of the base, and a plurality of straight oblique wires tilted relative to the lateral wires,
the lateral wires and the straight oblique wires are connected to form a serpentine shape as a whole,
each of the heating cells further includes a first folded part where a corresponding one of the lateral wires and a corresponding one of the straight oblique wires are folded at an obtuse angle,
in the first folded part, an end of the lateral wire is connected to a first end of a straight inversely oblique wire, a second end of the straight inversely oblique wire is connected to a first end of the straight oblique wire, forming an acute angle or a right angle with respect to the straight oblique wire and a second end of the straight oblique wire is connected to a power supply wire,
each of the heating cells includes a second folded part where a corresponding one of the lateral wires and a corresponding one of the straight oblique wires are folded at an acute angle, the second folded part being juxtaposed to the first folded part, and
the second folded part is chamfered in correspondence with the straight inversely oblique wire.
