1. A pressure controller connected to a bag-like member, supplying fluid to the bag-like member, and controlling an internal pressure of the bag-like member, the pressure controller comprising:
a housing having a flattened shape with a first surface on which a display is installed and a second surface opposite to the first surface;
a pump disposed in the housing such that a discharge port through which the fluid is discharged is directed in a thinnest thickness direction of the flattened shape of the housing;
a control module disposed in the housing and controlling the pump such that the internal pressure falls within a predetermined range; and
a low thermal conductivity member disposed at a side opposite to the discharge port and between the pump and the second surface of the housing, the low thermal conductivity member having elasticity and permeability.
