27. A unit for dissipating heat from a heat-generating electric component included in electronic components mounted on a circuit board, the unit comprising:
a casing in which the circuit board is housed;
a heat dissipating member which is thermally conductive, made of a polymeric material having fluidity, and is placed to receive heat generated from a heat-generating electronic component on the circuit board and to dissipate the received heat via the casing, wherein the heat dissipating member has two surfaces, one of which is in direct contact with the heat-generating element or the circuit board; and
a shift preventing member which prevents the heat dissipating member from being physically shifted to the casing by using a bonding force generated by chemical bonding involving the heat dissipating member.
