Abstract
The present invention provides a sensor and a method of producing the same, which makes an electrical connection condition between an electrode terminal section of a detection element and a metallic terminal member good. The sensor includes a lead frame (metallic terminal member) that changes a support condition of supporting an element abutment section for contact with a detection element on a frame main body section, into a one-point support or a two-point support. At a first-half stage of a work for assembly of the lead frame and the detection element, the element abutment section is put in a one-point support condition relative to the frame main body section and the lead frame produces a relatively smaller resilient force, such that it becomes possible to prevent an excessively large pressure from being applied to the detection element. After the assembly work is completed, the element abutment section is put in a two-point support condition relative to the frame main body section and the lead frame produces a larger resilient force as compared with that in the one-point support condition, such that the electrical connection condition between the lead frame and the detection element can be good.
