摘要：An electrical heating apparatus has: a fin (12) brazed on at least one of a mainbody upper wall (111) and a main body lower wall (112) of a tube (11); an insertion unit
(20) having an electro-heat-generating element (22) pressure-welded to a wall of one ofthe main body upper wall (111) and the main body lower wall (112); and an edge part(114) projected in the width direction from each of main body vertical walls (113) to forman edge space (11b). The edge space (11b) is formed so as to be continuous with theinsertion space (11a) and is smaller in thickness dimension than the thickness dimensionof the insertion unit (20). The edge part (114) has an edge part upper wall (114a), an edgepart lower wall (114b), and an edge part vertical wall (114c) disposed in a concave shape.
