Abstract: An electronic component includes a case body, an electronic circuit, and a conductor portion. The case body is formed by fitting a first housing and a second housing. The electronic circuit board is accommodated in the case body. The conductor portion is formed to continuously extend in a circumferential direction of the electronic circuit board at a portion of the first housing where the first housing is fitted to the second housing. The conductor portion is electrically connected to a ground of the electronic circuit board.
