Internal combustion engine

An internal combustion engine which includes:

• an intake passage fuel injection valve for injecting fuel into an intake passage;
• and a cylinder inside fuel injection valve for injecting fuel into a combustion chamber, the internal combustion engine comprising:
• a fuel pump which is configured to pressurize and feed fuel, which is fed from a fuel tank, to the cylinder inside fuel injection valve;
• a securing part which is provided on a cylinder head member of the internal combustion engine to secure the fuel pump;
• an introducing member having heat conductivity, the introducing member which is connected to the fuel pump, and which is formed with:
• a first introducing path for introducing fuel from the fuel tank to the fuel pump;
• and a second introducing path for introducing fuel from the fuel tank to the intake passage fuel injection valve;
• and
• a heat transmitting member which is configured to transmit heat between the introducing member and the securing part.
