Electronic component
A method of manufacturing an electronic component includes temporarily fixing an electronic component body to a support with a temporary fixation material having an area smaller than that of the electronic component body interposed therebetween, disposing a shield resin layer having an area larger than that of an upper surface of the electronic component body on the upper surface of the electronic component body, and applying pressure to the shield resin layer via an elastic layer and causing the shield resin layer to adhere such that the shield resin layer extends from the upper surface that is the surface of the electronic component body opposite to the temporary fixation material to a bottom surface that is a surface of the electronic component body that faces the temporary fixation material via side surfaces of the electronic component body.
