The invention provides an electrostatic capacitance type sensor which can be manufactured without using a volatile adhesive and an organic solvent. The present invention is provided with: a first electrode sheet provided with a plurality of first through-holes; a dielectric layer having a first surface disposed on the first electrode sheet side; and a first welding layer which is formed of a welding material, and which, by welding the welding material, joins the main body portion of the dielectric layer and the boundary portion of the first inner surface of the first electrode sheet, and joins the main body portion of the dielectric layer and the boundary portion of the first inner peripheral surface of at least a portion of the plurality of first through-holes. The dielectric layer is formed of a thermoplastic material, the first fusion layer uses a portion of the dielectric layer as a fusion material and joins the boundary portions by fusion of the portion of the dielectric layer, and the first fusion layer is formed of the same material component as the dielectric layer. The first welding layer is welded over the entire range where the main body portion of the dielectric layer and the first inner surface of the first electrode sheet face each other.

    本发明提供静电电容型传感器,其能够不使用挥发型粘接剂及有机溶剂地制造。其具备:第一电极片,其具备多个第一贯通孔;电介质层,其第一面配置于第一电极片侧;以及第一熔接层,其由熔接材料形成,且通过熔接材料的熔接而将电介质层的主体部分与第一电极片的第一内表面之间的边界部位接合,以及将电介质层的主体部分与多个第一贯通孔的至少一部分的第一内周面之间的边界部位接合,电介质层由热塑性材料形成,第一熔接层将电介质层的一部分用作熔接材料,并通过电介质层的一部分的熔接将各个边界部位接合,第一熔接层由与电介质层相同的材料成分构成,第一熔接层在电介质层的主体部分与第一电极片的第一内表面相对置的整个范围进行熔接。
