Provided is a method of manufacturing a porous protective layer for a gas sensor. The porous protective layer according to one Example of the present invention is manufactured by a method of manufacturing a porous protective layer for a gas sensor including (1) a step of introducing a composition for forming a porous protective layer including a pore former and a ceramic powder, which includes particles having a degree of deformation of 1.5 or more expressed by the following Relational Formula 1 according to the present invention, onto a sensing electrode for a gas sensor, and (2) a step of sintering the introduced composition for forming a porous protective layer.
A method of manufacturing a porous protective layer for a gas sensor, the method comprising:
A porous protective layer for a gas sensor comprising ceramic powders having a degree of deformation of 1.5 or more expressed by the following Relational Formula 1,
A porous protective layer for a gas sensor, which protects a sensing electrode of a gas sensor, wherein the porous protective layer includes through pores passing through a first surface facing a sensing electrode and a second surface opposite to the first surface, and the through pores have a diameter which increases from the second surface of the porous protective layer to the first surface.
