Zusammenfassung:	To create a fuel injection valve of a new type, reduced in leakage of both of a fuel and a coolant.SOLUTION: An outer seal surface (25) and at least one inner seal surface (26) separated from the outer seal surface (25) by at least one recessed portion (24), are formed on an end surface (11a) of a nozzle body (11) and/or an end surface (12a) of a nozzle holder (12), that is, the end surface (12a) adjacent to the end surface (11a) of the nozzle body (11), each inner seal surface (26) seals a fuel supply line (15) communicated therewith in a region of the end surfaces adjacent to each other, and each outer seal surface (25) seals a coolant supply line (22) and a coolant discharge line (23) communicated therewith in a region of the end surfaces adjacent to each other.SELECTED DRAWING: Figure 1 【課題】燃料及び冷却剤の双方の漏れを低減した新しい種類の燃料噴射弁を作成する。【解決手段】ノズルボディ（１１）の端面（１１ａ）及び／又はノズルホルダ（１２）の端面（１２ａ）であってノズルボディ（１１）の端面（１１ａ）に隣接する端面（１２ａ）には、外側シール面（２５）と、少なくとも１つの凹部（２４）により外側シール面（２５）から分離された少なくとも１つの内側シール面（２６）と、が形成され、それぞれの内側シール面（２６）が、互いに隣接する端面の領域でそれぞれの連通する燃料供給ライン（１５）をシールし、それぞれの外側シール面（２５）が、互いに隣接する端面の領域でそれぞれの連通する冷却剤供給ライン（２２）及び冷却剤排出ライン（２３）をシールする。【選択図】図１
