The seal structure for sealing between two members in a fluid-tight or air-tight manner is structured such that the seal portion is formed in at least one of joint surfaces of the two members by continuously printing along a seal portion of the joint portions and that a recess portion or a groove is formed at a middle portion of the seal portion in a widthwise direction.
