1. An electronic device comprising:
a circuit board on which an electronic component is mounted;
a housing that has an opening portion and accommodates the circuit board;
a connector that includes a connection terminal that enables electrical connection of the circuit board to an external connector, and a connector housing that holds the connection terminal and closes the opening portion of the housing, and has a communication hole that penetrates the connector housing and allows an internal space and an external space of the housing to communicate with each other; and
a filter which is attached to the connector housing so as to cover a first opening of the communication hole, the first opening being open to an internal space side of the housing and through which air passes,
wherein the connector housing includes a shielding wall that surrounds a periphery of a second opening of the communication hole, the second opening being open to an external space side of the housing, and protrudes toward the external space side of the housing from the second opening of the communication hole,
wherein the connector housing includes a plurality of connector fitting portions that have tubular shape, protrude toward an external space side of the housing, and is fitted to the external connector,
the connector fitting portions are disposed at intervals from each other, and
the communication hole is formed such that the second opening is positioned between a first connector fitting portion that is one of the connector fitting portions and a second connector fitting portion adjacent to the first connector fitting portion,
wherein the shielding wall includes a first wall portion, a second wall portion provided at a position facing the first wall portion, a third wall portion connecting the first wall portion and the second wall portion, and a fourth wall portion provided on a side opposite to the third wall portion across a position of the communication hole and connecting the first wall portion and the second wall portion,
the first wall portion is configured by a part of the first connector fitting portion, and
the second wall portion is configured by a part of the second connector fitting portion,
wherein in each of the third wall portion and the fourth wall portion, a portion located between both end portions connected to the first connector fitting portion and the second connector fitting portion is bent in a direction away from the communication hole.
