Abstract: An electronic component according to an aspect of the present disclosure includes an element body and a terminal electrode. The element body includes an outer surface provided with a depression. The terminal electrode is disposed on the element body. The terminal electrode includes a first electrode portion and a second electrode portion. The first electrode portion is disposed in the depression. The second electrode portion protrudes from the depression. The second electrode portion is thicker than the first electrode portion.

Abstract: To provide a simple structured and low cost pintle injector capable of uniformly atomizing and mixing fuel and oxidizer, and further improving the combustion efficiency of the combustion reaction in the combustion chamber. A pintle injector part having a first propellant channel forms a first injector flow path as a regenerative cooling path along the pintle external wall that projects into a combustion chamber, and high temperature fuel gas is injected from the first pintle injector port. On the other hand, an axial injector part is located upstream of the first pintle injector port, and injects comparatively low temperature liquid or gas fuel from an axial injector port via a third propellant channel and a third injector flow path. Oxidizer is injected from a second pintle injector port via a second propellant channel and a second injector flow path, and is atomized and mixed while being impinged on either by the high temperature fuel gas and the comparatively low temperature liquid or gas fuel.
