Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel high pressure pump which inhibits pressure pulsation.SOLUTION: The invention relates to a fuel high pressure pump (10) having a pump plunger (26). The pump plunger (26) translates between a compression chamber (20) and a leakage chamber (24) during operation. The leakage chamber (24) has a leakage collection area (34) and a compensation area (40). A lower pressure damper (58) including a damper plate (60) which is formed into a waved shape to make a bellows form is disposed in the compensation area (40).SELECTED DRAWING: Figure 1 【課題】圧力脈動を抑制する燃料高圧ポンプを提供する。【解決手段】本発明は、ポンププランジャ（２６）を有する燃料高圧ポンプ（１０）に関し、ポンププランジャ（２６）は、作動時に加圧室（２０）と漏れ室（２４）との間を並進運動し、漏れ室（２４）は、漏れ捕集領域（３４）および補整領域（４０）を有しており、補整領域（４０）には、ベローズ状に波形を付けられたダンパプレート（６０）を備えた低圧ダンパ（５８）が配置されている。【選択図】図１
