In order to provide a fuel pump configured so that, in order to effectively prevent the generation of fuel vapor, heat transferred to the pump body is less likely to be transferred to fuel within the pump body, the fuel pump is provided with: the pump body (11) which has formed therein a suction path (11a) and a fuel pressurization chamber (15); and pressurization pump mechanism (20) which has an outer end section (12b) lubricated by oil and which pressurizes and discharges the fuel within the fuel pressurization chamber (15) by power inputted to the outer end section (12b). The pump body (11) has a fuel receiving section (23b) in which a part of at least the suction path (11a) is formed, and a barrier section (25b) which restricts oil from flowing to the fuel receiving section (23b) side. A heat transportation member (45) which has higher heat transfer performance than a material which forms the pump body (11) is disposed in the heat transfer path between the fuel receiving section (23b) and the barrier section (25b). The heat transportation member (45) has a connection section (45c) exposed to the outside of the pump body (11).
