Abstract: Disclosed herein is an electronic component that includes a substrate, a planarizing layer covering a surface of the substrate, a first conductive layer formed on the planarizing layer and having a lower electrode, a dielectric film made of a material different from that of the planarizing layer and covering the planarizing layer and first conductive layer, an upper electrode laminated on the lower electrode through the dielectric film, and a first insulating layer covering the first conductive layer, dielectric film, and upper electrode. An outer periphery of the first insulating layer directly contacts the planarizing layer without an intervention of the dielectric film.

Abstract: An electrical connection box includes: a frame accommodating electronic components; and a lower cover located below the frame and closing a lower opening. The frame includes double walls including a first outer wall and a first inner wall and formed along the lower opening. The lower cover includes: a second outer wall located between the first outer wall and the first inner wall in a placement state; and a second inner wall formed inside the second outer wall and along the second outer wall. The first inner wall includes: a body formed in such a manner that a lower end is located between the second outer wall and the second inner wall in the placement state; and a bulge protruding toward the first outer wall from an opposed surface, being opposite to the first outer wall, of the body.
