To provide a conductive paste that is baked at a low baking temperature to give a primer electrode layer being compact and well bonded to a laminate.SOLUTION: A conductive paste 1 has a conductive powder 2 having at least one element selected from Cu and Ni, glass powder 3, and organic material 4. The glass powder 3 has a borosilicate glass composition with a softening point of 455°C or higher and 650°C or lower. A mass spectrum obtained by the mass spectrometry of a gas evolved when a mixture of the glass powder 3 and a C powder is heated and raised in temperature has a gas evolution peak with a mass number of 44 at 470°C or higher and 680°C or lower.SELECTED DRAWING: Figure 1 【課題】低い焼き付け温度で緻密な、かつ積層体との接合性の高い下地電極層を得ることができる導電性ペーストを提供する。【解決手段】導電性ペースト１は、ＣｕおよびＮｉの中から選ばれる少なくとも１種類の元素を含む導電性粉末２と、ガラス粉末３と、有機材料４とを備える。ガラス粉末３は、軟化点が４５５℃以上６５０℃以下であるホウケイ酸系ガラス組成物を含み、かつガラス粉末３とＣ粉末との混合物の昇温加熱時に発生するガスの質量分析により得られるマススペクトルは、４７０℃以上６８０℃以下に質量数４４のガス発生ピークを有する。【選択図】図１
