1. An electromagnetic relay comprising:
a case including a base with a terminal support portion;
a first fixed terminal supported by the terminal support portion, the first fixed terminal including a first fixed contact disposed apart from the base in a first direction inside the case; a contact support portion disposed between the first fixed contact and the terminal support portion and supporting the first fixed contact; and a first extending portion extending at an angle from the contact support portion and penetrating the base in a penetration direction that is opposite to the first direction;
a movable contact piece including a first movable contact facing the first fixed contact in the penetration direction;
a gas inflow space formed between the terminal support portion and the contact support portion inside the case; and
a gas passage penetrating the terminal support portion in the penetration direction and establishing communication between the gas inflow space and an outside of the case;
wherein the gas passage and the gas inflow space are overlapped by the contact support portion of the first fixed terminal when viewed from the penetration direction and are positioned beneath the contact support portion of the first fixed terminal, with the gas passage extending through the terminal support portion.
