ルトリメトキシシランなどが挙げられる。As the silane coupling agent, any commercially available silane coupling agent can be used depending on the binder resin and conductive material powder constituting the thick film electrode. Methoxysilane, γ-mercaptopropyltrimethoxysilane,
Examples include vinyltris(2-methoxyethoxy)silane, γ-glycidal bovine dipropyltrimethoxysilane, γ-methacrylic bovine dipropyltrimethoxysilane, and γ-aminopropyltrimethoxysilane.

特性の劣化を生じさせるからである。The intervening amount of the silane coupling agent is 0.2 to 3.0% of the total amount of the binder resin and conductive material powder that constitute the thick film electrode.
The reason why it is set as 0ffifft% is that the amount of the intervention is 0.2ff.
If the amount is less than 3.0ffif%, the effect of improving the electrical properties and adhesive strength cannot be expected sufficiently;
This is because if it exceeds fi%, the specific resistance of the electrode increases and the ohmic characteristics deteriorate.
