Summary:PROBLEM TO BE SOLVED: To provide a technique for suitably arrange a grounding terminal for grounding a control circuit in a fuel pump.SOLUTION: A fuel pump 10 is driven by a brushless motor. The fuel pump 10 comprises: a core 90; three supply terminals 72-76 for supplying power to a coil wire 96 fixed to the core 90 and wound around the core 90; a resin layer 62 that holds the three supply terminals 72-76; and a grounding terminal 78 held by the resin layer 62 while being insulated from the three supply terminals 72-76 and electrically connected to a control circuit for controlling power to be supplied to the three supply terminals 72-76. 【課題】 制御回路を接地するための接地端子を、燃料ポンプに適切に配置するための技術を提供する。【解決手段】 燃料ポンプ10は、ブラシレスモータで駆動される。燃料ポンプは10は、コア90と、コア90に固定されており、コア90に巻回されているコイル線96に電力を供給するための3個の供給端子72〜76と、3個の供給端子72〜76を保持する樹脂層62と、3個の供給端子72〜76に対して絶縁されている状態で樹脂層62に保持されており、3個の供給端子72〜76に供給される電力を制御するための制御回路に電気的に接続される接地端子78と、を備える【選択図】 図5
