Title: MAGNETIC FIELD DETECTION DEVICE
Abstract:
This magnetic field detection device has an IC package (20), a terminal (30), and a resin molded body (40). The IC package has a magnetic detection element (21), a lead frame (22) positioned on the first side of the magnetic detection element, and a resin material (23) covering the magnetic detection element and the lead frame. The terminal is connected to the lead frame of the IC package. The resin molded body has a base section (41) and a head section (42). The base section covers a connection area where the lead frame and the terminal are connected to each other. The head section covers the magnetic detection element of the IC package. The head section has the thickest portion. The outer wall surface of the thickest portion positioned on the second side of the magnetic detection element is defined as a detection-side reference surface (48). An element-corresponding surface (24) positioned on the second side, said element-corresponding surface being the outer wall surface of the IC package, is exposed from the resin molded body, or covered with a detection-side thin portion (46) that is thinner than a thickness (T4) from the element-corresponding surface to the detection-side reference surface.
